Red Chalcedony / Carnelian
This variety of chalcedony ranges from a medium/dark red with orange overtones; to a highly saturated, visually pure orange. It's one of the birthstones for July.
The name Carnelian - also known as Cornelian - comes from the Latin "cornum" meaning "cornel berry" or "cornelian cherry." The Roman historian Pliny declared that "among the ancients there was no precious gem in more common use." It has been heated for color enhancement since at least 2000 B.C. Most Carnelian on the modern market is also heat treated to enhance it's color. The darker, redder colors are preferred, and a translucent gem is more valued than an opaque gem. Carnelian's durability makes it a perfect choice for any kind of setting.
