What are the most frequently used Gem materials? And, what's the difference between transparent & translucent?
What are the most frequently used Gem materials? And, what's the difference between transparent & translucent?
According to the Encyclopedia Americana, the most frequently used gem materials are:
Amber, Beryl, Chrysoberyl, Coral, Corundum, Diamond, Feldspar, Garnet, Hematite, Jade, Lapis Lazuli, Malachite, Opal, Pearl, Peridot, Quartz, Spinel, Spodumene, Topaz, Tourmaline, Turquoise and Zircon.
The Encyclopedia Americana's bibliographies on this information were dated from 1947 to 1965; and the Encyclopedia was copyrighted in 1969.
It's 2008 now... have there been new changes on this list? If there are new changes on the list of frequently used gem materials, what are they? Were there new materials discovered? Were some of the said materials on the list of frequently used been removed? If so, what were they?
Please, help this aspiring mineralogist and gemologist!!
Please?????
Diamonds. They are extensively used as abrasives. Transparent = you can see through it. Translucent = you cant see through it but light passes through it.
