Precious gemstones – Diamond, Ruby, Sapphire, Emerald Semi-precious gemstones – Agate, Alexandrite, Amethyst, Aquamarine, Beryl, Citrine, Garnet, Opal, Spinel, Tanzanite, Topaz, Turquoise, Tourmaline, Zircon, Peridot When purchasing a gemstone there are the five characteristics to consider: COLOR – The color of a gemstone it its most defining feature. When deciding upon a gemstone color it is important to look at its hue, tone, and saturation. The jewelry industry as a whole recognizes the highest quality gemstones by their green, red, or blue hue, a medium to dark tone, and saturated color. The most valuable gemstones exhibit a pure color and only slight hues of other colors in addition to their primary color. Tone represents the depth of the color, which can range from colorless to black. The tone of a gemstone is described as “light”, “medium-light”, “medium”, “medium-dark”, and “dark”. Color purity, or saturation, refers to the degree in which the gem is free of brown or gray hues. The gemstones that are most sought after show little gray or brown and are often referred to as having vivid or strong color saturation.

CLARITY – Gemstones form under unique circumstances and each individual gemstone is comprised of a combination of trace minerals that create identifying marks or inclusions in the gemstone itself. Gemstones that are flawless are very rare and valuable and even the most high-end gemstones are at least slightly flawed. The best value is found in gems that are lightly to moderately included.

SIZE – Gemstones can be cut into a round, square, oval, or pear shape. The carat weight of a gemstone is not necessarily an accurate gauge for a gemstone only because all gemstones have different densities. Two gemstones that have the same carat weight may actually have a different weight.

ENHANCEMENTS – Almost all gemstones available have been enhanced. Gemstones that have not been enhanced are very recognizable because of their incredibly high cost. Some enhancements are an expected part of the polishing and finishing process and are accepted by the jewelry industry as a whole. Almost every ruby or sapphire that you would find has been heated. Heating completes a process that nature started, which is to enhance the gemstone to brilliant colors of blues and reds. Placing emeralds in oil has been going on for centuries and fills tiny fissures in emeralds to make them even more beautiful.

CUT – Color saturation determines a gemstones cut. A greater color saturation requires a shallow cut, while less color saturation requires a deeper cut. With gemstones you will not find an ideal cut that is geometrically configured for brilliance like diamonds. To determine if a gemstone is top quality or not, in terms of its cut, look at the setting and make sure that all the facets are symmetrical. An asymmetrical cut crown indicates a gemstone of low quality. A well-cut gemstone is symmetrical and reflects light evenly across the surface and the polish of the stone is smooth without any nicks.
