Blue chalcedony, the sky blue gemstone in designer jewelry
06.09.09
The most general forms of blue chalcedony are solid stones, cut first, then carved into beads with glossy, faceted, or textured surfaces in shapes of every possible genre. Blue chalcedony comes also in a few other forms. Botryoidal is the carbonation-like form that yields a wavy texturized outside that displays so nicely in designer
jewelry. Another form is druzy, which comes from the crystalline up-country of geode formations. Because it forms only on the inside surfaces of internal crag voids, druzy of any kind is not particularly abundant and is therefore exorbitant. Blue chalcedony comes predominately from sources in Africa, including Namibia and Malowi, in Turkey, and in the say of Washington. I get the blue chalcedony for my necklace designs from a few loyal sources in Tucson at the annual winter Gem Show. And, while I don’t remember the exact sources of my Gem Show sources, I would say the blue chalcedony I obtained from them was from Turkey. Not precisely because the vendors were Turkish fellows but because of the rich blue color property of chalcedony from quarries in West Anatolia. The blue in lewd chalcedony from other sources tends to be lighter and the stone more translucent.
