Chalcedony

Chalcedony, or calcedony, is a fine-grained variety of the silica mineral quartz. It has a waxy luster and appears in a great variety of colors - usually blue-white, buff, light tan, gray, yellow or brown. Chalcedony is named after the ancient seaport of Chalcedon (Kadikoy, Turkey). Archaeologists have dug up Babylonian and Assyrian chalcedony cylinder-seals dating from 500 BC. Common forms of chalcedony include agate, bloodstone, jasper, and onyx.

except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
