Gemstones
GemstonesJewelry wants you to understand what you're buying. The four most popular factors used to measure diamond quality are cut, color, clarity, and carat weight.Gemstones ColorThe highest quality gemstones are recognized by the jewelry industry by the purity of hue, depth of tone, and color saturation. Gemstone colors come in a variety of hues: one gemstone may have a variety of hues, and many gemstones may be available in any one hue. Prices for these varieties are based upon factors such as durability, rarity and popularity. Brighter, more vivid colors with a medium saturation are the most sought-after. Typically, very pale or dark shades, or gems with grey-tinged edges tinged are less expensive. However, personal tastes will drive desirability, regardless of price or popularity.Gemstone ClarityDue to the way gemstones form in the earth, almost all contain tiny fractures called inclusions. Generally, flawless gemstones are very rare and valuable, however even most high-end gemstones are at least slightly included. The best value is found in gems that are lightly- to moderately-included, yet some gemstones, like emeralds and red tourmaline, always have visible inclusions, so those inclusions detract less from their value. Certain inclusions can also indicate from where in the world the gemstones were mined. Clarity has the most impact on lighter-hued gemstones, because the inclusions are most visible.Gemstones CutGemstone cuts are similar to diamond cuts. However, unlike diamonds, with gemstones there isn't an "ideal" cut geometrically configured for maximum brilliance. A high-quality gemstone cut is one that presents the most even color, exposes the fewest inclusions, and displays the majority of the gemstone weight when set in jewelry.Gemstones SizeLike diamonds, gemstones are measured by the carat, which is one-fifth of a gram. Size sometimes, but not always, has an impact on the gemstone’s price. Gemstones like the Emerald, Ruby and Sapphire rarely occur in large sizes, so larger stones typically fetch higher prices. Amethyst, Citrine, Blue Topaz and Amber more frequently occur in large sizes, so a larger stone may be less pricy than the same sized Emerald. A one-carat Blue Topaz and a one-carat Ruby may be the same weight but not the same size, due to gemstone density.Gemstones EnhancementsNearly all colored gemstones available have been enhanced. Gemstones that have not been enhanced but exhibit desirable color and clarity are very recognizable by the extravagant price they command. Some enhancements, such as heating, are an expected part of the polishing and finishing process and are accepted by the jewelry industry, and by Jewelry Jewelry. |

Platinum has a much shorter history in the financial sector than either gold or silver, which to ancient civilizations. Platinum is relatively scarce even among the precious metals.
RubiesThe ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum. The red color caused mainly by the presence of the element chromium. Its name comes from ruber Latin for red. Other varieties of gem-quality corundum called sapphires. The ruby considered one of the four precious stones, together with the sapphire, the emerald, and the diamond. All natural rubies have imperfections in them, including color impurities and inclusions of rutile needles known as silk. Gemologists use these needle inclusions found in natural rubies to distinguish them from synthetics, simulants, or substitutes. Usually the rough stone heated before cutting. Almost all rubies today treated in some form, with heat treatment being the most common practice. However, rubies that are completely untreated but still of excellent quality command a large premium. The Price of rubies primarily is by color. The brightest and most valuable red called pigeon blood red, commands a huge premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone been treated. Cut and carat also determine the price. In the evaluation of colored gemstones, color is the single most important factor. Color divides into three components, hue, saturation and tone. Hue refers to color as we normally use the term. Transparent gemstones occur in the following hues: red, orange, yellow, green, blue, violet, purple and pink are the spectral hues. The first six are spectral hues; the last two are modified spectral hues. Purple is a hue that falls halfway between red and blue. Pink is a paler shade of red. In nature there are rarely pure hues so when speaking of the hue of a gemstone we speak of primary and secondary and sometimes tertiary hues. In ruby the primary hue must be red. All other hues of the gem species corundum called sapphire. Ruby may exhibit a range of secondary hues. Orange, purple, violet and pink are possible. |
