ROCK TRIVIA: EMERALD
Not only is Emerald is the most precious stone in the beryl group, gem quality emeralds are more valuable than diamonds. More than any other colored gem, color is the biggest factor of value in Emeralds. The most popular and valuable color is a slightly bluish green in a medium dark tone with strong saturation. Too blue or too yellow decreases the value of the stone. Unlike other gemstones where 10x magnification grades the clarity, if an emerald has no inclusions that are visible to the naked eye, it is considered flawless.
Colombia, Brazil and Zambia are the leading producers of gem quality emeralds, Leading the way, Colombia is famous for grass green emeralds. Brazilian has emeralds with fine clarity and a slightly yellowish green color and Zambian emeralds have a slightly bluish green color.
The necklace pictured was designed by Bulgari and given to Elizabeth Taylor by Richard Burton. The set includes stones that belonged to the Grand Duchess Vladimir of Russia.
