Carnelian is the stone for the tropical zodiac sun sign of Virgo. From the 15th century through the early 20th century, it was also considered a birthstone for the month of August. It’s also the birthday stone for anyone born on a Thursday.
Carnelian is a lovely deep red to orange red to reddish brown color, and is a member of the chalcedony family (we both say kal-SED-n-ee, but KAL-suh-doh-nee is correct too), which also includes agate, jasper, onyx, chrysoprase, and sard, amongst others. Chalcedony is a variety of microsrystalline quartz. Its hardness on the Mohs scale is 7.
Kay cabbed a piece of rough carnelian and polished it up, then set it in a gorgeously simple sterling silver size 6 band, to make the ring shown below – you can take a closer look at it by clicking here.
