This is the initiative to move to a more green lifestyle. I am an Earth Scientist and very passionate in starting my personal crusade to lower my carbon footprint and spread the word about green energy. Everything about wind, water, and solar will be discussed and explored. I will not stop until I have scavenged my bliss
Demantoid is the green gemstone variety of the mineralandradite, a member of the garnet group of minerals. Andradite is a calcium- andiron-rich garnet. The chemical formula is Ca3Fe2(SiO4)3 with chromium substitution as the cause of the demantoid green color. Ferric iron is the cause of the yellow in the stone.
In approximately 2003, reports began to circulate in the trade that some Russian Demantoid garnets were being routinely subjected to heat treatment in order to enhance their color. Such treatment is believed to be performed at relatively low temperatures and is thought not to be detectable by gemmological testing
