Gemstone Colors, What You Should Know
Gemstone Colors, Useful Information On The Colors Of Gemstones.
Many gem lovers choose a gem based on the color. Certain gemstones are favorites with men and ladies have their own choice when it comes to gem colors. It is true that the price, demand and availability of a gem are to a large extent influenced by the color of the gem stone. Many gems can have similar color but are totally different in terms of composition and physical properties. When talking about natural gemstones, not all the colors that you see are natural. The treatment of gemstones to change or enhance color is rampant, so much so that gemstone experts accept many of these treatments.
Some gemstones actually change color when the light source changes. These gems are referred to as color change stones and alexandrite leads the pack of such gems. Color change garnet is another stone that changes color when light is switched between daylight and incadescent light. Another color change that is visible in certain gems like iolite is diochroism or pleochroism. With this property a gem shows different colors when viewed from different angles. An iolite gemstone can show a deep saturated color from one angle, view the stone from another angle and you will see an almost colorless side of the stone.
When it comes to treating gemstones, various methods like radiation, heat treatment, oil treatment, wax treatment have been known for decades. As gemstones become rarer and prices move up, gem manufacturers have devised new methods to treat gemstones for color and clarity. Some of these treatments are unfortunately not explained to the buyer. The gem dealer then charges a high price for a treated gem that should be worth at least 90% less than the price at which it is really sold. This is the sad side of the gemstone and jewelry industry.
