Care With Gemstones

Care With Gemstones
By Kadence Buchanan

Gemstones are one of the most precious substances known to mankind. Their worth alone is reason enough for us to care for them. A gemstone can cost a fortune and one scratch or impurity can ruin there value. As strong and durable as they may be, they can be scratched, dirtied and even broken if mishandled. There is not much we can do to care for them, but some precautions are necessary.

Physics teaches us that no matter how hard a substance is, it can be broken down to bits if applied some pressure at the right points. During exercise, we sometimes strain our muscles at various points, particularly our fingers. Therefore it is advisable to remove any rings before attempting any strenuous exercise.

Cleaning gemstones requires a simple knowledge about gemstones. There are generally two kinds of gemstones; transparent and opaque. Transparent gemstones will make dust visible even if it gathers behind the stone on the ring or any form of jewelry that holds them. These are mostly single crystal stones and therefore application of water will not affect them too much. The use of a soaked cloth to clean the dust gather behind the stone is therefore not a bad move. You may even use a brush to clean the dust if you like.

However, opaque gemstones or organic gemstones are affected by water or any chemical substance. These are usually porous and will allow the water or chemical to flow inside the gemstone. Once inside they can either build up inside, make the stone loose its color or even cause it to crack. Therefore these kind of gemstones should be kept away direct contact with any kind of chemical in sprays, cosmetics and even from water.

There are advanced methods using certain technology to help clean gemstones. Expert jewelers and dealers are well-versed with all these methods and know how to clean each specific kind of gemstone. Therefore it is advised that you do not do the cleaning yourself and rather, have it done by someone who knows more about how to deal with them. If you can afford to buy a gemstone, why not spend a little more money on keeping them safe and clean?

Gemstones are hard materials. In contact with some other gemstone or the metals which contain them such as gold, they can crack each other or the metal. Therefore care must be taken with jewelry how it is kept and handled. Jewelry is expensive and valuable, especially those with precious gemstones in them, therefore they should be treated with care.

Gemstones - Girl's New Best Friend?
By Alan Ross

Colorful gemstones are just anybody’s dream to have. Their natural colors more than match your very fashionable dresses. Their sheer range could strike you spell bound. Gemstones are precious or semiprecious mineral stones which when cut and faceted can be used as jewels.

There is more to gemstones than just being jewelry items. They are regarded as lucky when worn specific to an individual’s birth month. Before we deal with this aspect in detail lets see the classification of gemstones.

Classification and Characteristics of Gemstones

There is a tri-level classification of gemstones namely, groups, species and varieties. Simply put, rubies which are red in color belong to conundrum species which in turn belong to hematite group. Others like emerald, aquamarine, goshenite, heliodor and morganite, all of them belong to that variety known as beryl. There are over 150 different species available.

Gemstones display all characteristics of crystals like dispersion, refractive indices, hardness, and specific gravity etc. They also possess characters like inclusions, fractures and cleavage which play upon their quality and values. However gemologists include all gems into the precious list.

Hardness is another important characteristic of gemstones. Simply put, hardness means resistance to scratch which is measured in Mohs, a system developed by an Austrian mineralogist F. Mohs. The scale of hardness reads from 1-10 with higher number indicating the hardest. If talc is at the bottom with just 1Moh, diamond has 10Mohs. Other popular gemstones like feldspar, topaz and sapphire having Mohs of 6, 8 and 9 respectively.

Birth Stones

US Geological Survey lists gemstones classified as birth stones. It is believed by most people that wearing birthstones brings luck to their lives. It is not surprising that all societies have this kind of faith with regards to gemstones, albeit with differences here and there, looking at the romancing tryst every society had with these ‘stones’. The list is in the order of calendar months with each month having at least one gemstone specific to that month. One can find a list of birth stones on official website of USGS.

Buying Gemstones

USGS cautions buyers against unscrupulous sellers as more and more of them are trying to push through synthetic gemstones as genuine pieces to unsuspecting, inexperienced buyers. Gemstones are measured by size and carats. (1carat=1/5th of a gram.)

When buying gemstones, watch out for:

1. Heating alters the color sometimes improving clarity

2. Irradiation darkens colors

3. Impregnation with wax, resins etc fills cracks, flaws

4. Fractures filled by injecting plastic

5. Differential colors in center and surface indicates diffusion treatment

Always buy from reputed sellers who produce certificates by Gemological Institute of America to prevent a lucky stone turn unlucky.

Color Change or Color Shift Gemstones

Color Change or Color Shift Gemstones - Not Knowing The Difference Can Cost You Money
By Derek Parnell

One of the most exciting and interesting gemstones you can buy is one that has color change, Alexandrite is most recognised of these gemstones as it has a dramatic color change depending on your light source. Today there are a lot of color shift gemstones, being sold as color change. Usually a color change gemstone commands a premium price, so how can you be sure you are getting color change and not color shift?

All of a gemstones color (hue, tone and saturation) is dependent on two things, how the gemstone is cut and the most important component light. It is the type of light and direction of the light that produces the brilliance and fire in a well-cut diamond or the beautiful color in gemstones.

The color you see in a gemstone is the result of the light that returns to your eyes after bouncing off the gemstones crystal structure. Now we know what causes color but what makes it a color change or color shift gemstone?

Click Here For The Best Loose Gemstone Auction Deals

The element chromium that allows equal amounts of red and green light to pass through it causes color change in Alexandrite. Because of this balance of red and green, if you view Alexandrite under incandescent light (rich in red) the gemstone looks like a red Ruby. If you then take the gemstone and hold it under an incandescent light (rich in blue/green) the Alexandrite looks more like an Emerald Green. This is color change.

Color shift is representative of colors that can change in the different or the same light source, a good example of this would be Tanzanite that will shift from blue to violet/purple by tilting the gemstone in the same light source. You will find a reasonable amount of gemstones will have this effect especially the ones with rich colors,

The best explanation of the difference I have used for deciding what is color change and what is color shift, is for those that have seen or have access to color grading wheel which is a chart that designates all of the colors of gemstones for grading gemstones. GIA calls it the hue wheel and it shows all of the color hues from Blue, to Green, to Yellow, to Orange, to Red, to Purple, to Violet (32 hues in all). If a color change moves from Red to the next color on the wheel (orange) then this is called a Color Shift. If the color moves from Red to Green, which is on the other side of the wheel, then this is called Color Change.

Some of the major natural Color Change gemstones are Sapphire, Ruby, Alexandrite, Spinel, and Garnet. Also be aware, today there are a lot of coated or diffused gemstones that will also show color change.

What You Should Know About Choosing Your Gemstone
By Eric Hartwell

Gemstone jewelry has always been a favorite accessory of women. Diamonds have always been women’s best friend, but gemstones are becoming popular because of their radiance, which radiates to the women wearing them. The appeal of gemstones is that they make the women wearing them feel as beautiful as they are.

Gemstone jewelry come in so many variety that sometimes the task of choosing the gemstone is more daunting than the actual task of buying the jewelry. Whether you would be buying gemstone jewelry for yourself or for somebody else, you have to take the time to have a basic knowledge of gemstones and be able to evaluate gems and metals to be able to make a wise purchase or wise investment. You also have to learn to recognize a real gemstone from a synthetic or an imitation. There are gemstones that are very rare, and these rare gemstones are more valuable and an asset than other stones. The appearance of a gemstone is its primary attribute, which determines the price it would sell in the market.

Kinds of Gemstones

There are many kinds of gemstones, the five most popular are the diamonds, pearls, emerald, ruby, and sapphire. Before going out and purchasing gemstone jewelry, you must be able to determine if one is fake or real. Know the difference between a glass or a diamond, and faux pearls from real ones. Know what color is a ruby, an emerald or a sapphire.

Diamonds are valued according to their color, clarity, cutting, and carat. If a diamond is more colorless, with lesser or no marks, is beautifully cut, and is larger in size, chances are, it is of best quality and probably would be very expensive.

Pearls, on the other hand, are so varied that seemingly no two are ever the same. Pearls could either be natural or cultured but always be alert that you do not purchase an imitation pearl.

You would always know an emerald from a ruby as an emerald has a green velvety glassy color and texture while a ruby has always been famous as the red gemstone. Emeralds are fragile as they can break easily and is in need of most care than other gemstones.

Sapphires vary in color to yellow, blue, green, orange, pink, and purple.

Choosing Your Gemstone

There are still a lot of other kinds of gemstones. Prices could range from very expensive ones to prices which you can generally afford without putting too much dent on your wallet or your credit card. Choose, therefore, according to the size of your wallet or your bank account. Whatever you intend to choose and purchase, the important thing to remember is that the gemstone must be lasting and enduring.

Caring for the Gemstone of Your Choice

If the gemstone needs special care, accordingly, the same care should be given. Exposure to chemicals or sunlight could harm these stones and reduce the value which you highly paid for. Gemstones would always make you feel as beautiful as they are, and that is what you would be paying for.

Gemstones - Production, Purity and Price
By Eric Hartwell

Beauty is everything. More than a thousand years of civilization and education have proven this saying false. However, in the case of selecting, collecting and donning gemstones, while beauty isn't the only factor considered, it has a very large role. Although gemstones are subjected to several examinations and scientific standards, the eyes remain to be the best judge.

These pretty things, no matter how small, can be the price of one laptop, or even a car. Yes, they can be expensive sometimes. But a lot of work and preparation goes in to the development and finish of a gemstone.

Gemstones are actually rocks or minerals which are cut and polished before distributed commercially. They may also be petrified materials, meaning they are made of organic material and are transformed to stones or other similar materials. Other gemstones, which are of organic material, do not undergo petrification, thus they remain organic.

Gemologists are scientific experts who evaluate gemstones using a set of procedures. They assess the gemstones based on several standards such as their chemical composition, value and presence of flaws.

The chemical composition of gemstones plays a significant role in evaluating them as there is a different chemical composition from one gemstone to another. Diamonds, for instance, largely contain carbon, which may not be present in other gemstones.

Value is another factor considered in the evaluation and pricing of gemstones. The rarity of gemstones is a large contributing factor in their value. The rarer the gemstone, the higher is its value. Most of the features of gemstones which contribute to their beauty are also factors of value. Such features of beauty are their color, form, visual appeal and also rarity. Again, the rarer the features of these gemstones, the higher usually are their price. For example, although there are colored diamonds distributed commercially, the colorless ones are the most expensive as they rarely occur in nature or are rarely harvested. Other gemstones may be more expensive when they have bigger sizes if smaller ones are usually the ones harvested.

The presence or absence of flaws in gemstones is, needless to say, very significant. Collectors, jewelers and other consumers prefer those with no flaws. However, in some cases, the presence of flaws usually confirms the authenticity or naturalness of gemstones. One considered flaw of gemstones is blemish. Blemish is a flaw or defect which is present at the surface of gemstones. This may be a scratch, a chip or a pit. Another flaw is inclusion which probably is a testament to the adage saying that beauty is skin deep. It is a defect within gemstones and may be in the form of a cloud, bubble, fracture or grain.
Gemstones undergo various treatments to enhance their beauty, particularly their color and clarity. They may be subjected to heat, radiation, waxing or coating. Some treatments are effective in enhancing the value of certain gemstones, while others are not stable, therefore are not widely accepted.

Synthetic Gemstones and Imitations, What You Need to Know?

Synthetic Gemstones and Imitations, What You Need to Know?
By Derek Parnell

In the 18th Century the chemical make up and structure of gemstones became of interest in those who wanted to create these beautiful gemstones. By the end of the 19th Century scientists were duplicating crystals with appearance and physical properties of their natural counterparts. Laboratories grew up devoted to synthesizing some of the most common and valuable gemstones we see today.

Many consumers today purchase synthetic gemstones as part of their jewelry collection, as they are low cost and the quality of some synthetics are excellent. The challenge comes when synthetic gemstones are either deliberately or through lack of knowledge sold as natural gemstones. This article will discuss some of the more common varieties of synthetic gemstones, so that you can be aware they do exist. Most will require a gemologist or a laboratory to be able to detect if the gemstone is real or synthesized. If you are not sure have the gemstone authenticated by a gemologist or a reputable grading laboratory like GIA or EGL, two of the worlds leading authority on gemstones.

There are many different ways to synthesize gemstones and as the processes are very technical I will just mention some of them by name only. These are Flame Fusion, Pulling, Floating Zone, Skull Melt, Flux Growth, and Hydrothermal Growth. These processes can produce synthetic gemstones such as Ruby, Sapphire, Spinel, Alexandrite, Cubic Zirconia, Emeralds, Amethyst, Opal, Turquoise, Lapis and many others.

One of the key developments of synthetic Ruby was to accelerate the growth and reduce the cost of components for Lasers. Today, nearly all ruby lasers use synthetic Ruby. These lasers are used in everything from your supermarket scanner to Medical Diagnostic Tools.

From Synthetic to imitations, these can be either man made or other natural gemstones. For example Red Spinel can imitate Red Ruby, Amethyst can imitate Tanzanite, Garnet can imitate Ruby. Most people will associate color with a gemstone and make an assumption that if is has a rich red Ruby color it is Ruby.

In the previous paragraph we discussed how laboratories can product synthetic versions of the real gemstone. It is also common to see synthetic gemstones used to imitate other natural gemstones. Synthetic Sapphire has been used to imitate Tanzanite by changing its color in the synthesizing process. Glass is probably the largest imitator of them all, as it can imitate most gemstone colors and is very cheap to produce. You will also see a lot of plastics used to imitate, Turquoise, Malachite, Peal, Amber, Jade etc.

One other set of imitations are assembled stones, these assembled gemstones use combinations of natural and synthetic material, to produce the desired effect. This process involves making gemstones of 2 or 3 different materials and cementing them together. An example might be a Sapphire and Synthetic Ruby Doublet, where the crown is Natural Sapphire and the pavilion is synthetic Ruby. To the unaided eye it looks like the natural gemstone but to a trained eye the assembled stone will soon reveal its secrets.

Should you buy Synthetic or Imitation gemstones? Absolutely, as they offer good value and you can assemble a colourful collection of them to match your mood and accessories at a very low cost.

Just make sure that you are aware that when you purchase a natural gemstone that you do not receive an imitation or a synthesized version.

Buying Gemstone Jewelry For Your Business

Buying Jewelry For Your Business Part 3: Buying Gemstone Jewelry
By Sam Serio

Whether you presently own a retail or web based business and are looking for an additional profit center or you are thinking of starting a business, jewelry is a “no-brainer” choice for a proven product category. The buying public, (particularly women) never tires of jewelry as the choices in color, materials, finishes and styles are endless and innovations are continual. Every generation reinvents jewelry for itself in much the same way that it reinvents music and fashion. Styles change but the basic facts remain the same. If you are a seasoned professional, please consider the following a refresher course. To the new comer, use this information as a foundation for your ongoing jewelry education.

The Facts About Gemstone Jewelry

Natural gemstones are found in nature. Laboratory-created stones, as the name implies, are made in a laboratory. These stones, which also are referred to as laboratory-grown, {name of manufacturer} - created, or synthetic, have essentially the same chemical, physical and visual properties as natural gemstones. Laboratory-created stones do not have the rarity of naturally colored stones and they are less expensive than naturally mined stones. By contrast, imitation stones look like natural stones in appearance only, and may be glass, plastic, or less costly stones. Laboratory-created and imitation stones should be clearly identified as such.

Gemstones may be measured by weight, size, or both. The basic unit for weighing gemstones is the carat, which is equal to one-fifth 91/5th) of a gram. Carats are divided into 100 units, called points. For example, a half-carat gemstone would weigh .50 carats or 50 points. When gemstones are measured by dimensions, the size is expressed in millimeters (for example,
7x5 millimeters).

Gemstone treatments or enhancements refer to the way some gems are treated to improve their appearance or durability, or even change their color. Many gemstones are treated in some way. The effects of some treatments may lessen or change over time and some treated stones may require special care. Some enhancements also affect the value of a stone, when measured against a comparable untreated stone.

Jewelers should tell you whether the gemstone you’re considering has been treated when: the treatment is not permanent; the treated stone requires special care; or the treatment significantly affects the value of the gemstone.

Some common treatments that you may be told about and their effects include:

• Heating can lighten, darken or change the color of some gems, or improve a gemstone’s clarity.

• Irradiation can add more color to colored diamonds, certain other gemstones and pearls.

• Impregnating some gems with colorless oils, wax or resins makes a variety of imperfections less visible and can improve the gemstones’ clarity and appearance.

• Fracture filling hides cracks or fractures in gems by injecting colorless plastic or glass into the cracks and improves the gemstones’ appearance and durability.

• Diffusion treatment adds color to the surface of colorless gems; the center of the stone remains colorless.

• Dyeing adds color and improves color uniformity in some gemstones and pearls.

• Bleaching lightens and whitens some gems, including jade and pearls.
