Burnt, and irradiated stones such as most citrine and amethyst sold today, do not have the same metaphysical qualities of the earth-born, genuine gems, but can have more visual and certainly economic appeal. However, such gems are commonly passed off as genuine, and became popular because the more pale colored unenhanced varieties are elusive, more costly, and often difficult to obtain. It is required by the Federal Trade Commission (FTC in USA) to disclose all enhancements to gem stones, and method of enhancement used if known. Buying your gems from a reputable dealer or crafts-person will avoid being misled when shopping. A seller should be able to tell you about a gemstone in their possession. However, if they can't tell, and your heart desires the piece anyway, then consider the purchase as a personal joy rather than a financial investment or metaphysical tool.
A fellow artist has recently presented an informative Internet lens for shoppers at a nifty site called Squidoo, (which allows you to share & learn about tons of different topics). The lens by Staci Rose is titled, Guide to Gemstones and Glass and Trust. Why not stop by her lens and see what she has to share too?
