Sardonyx - Birthstone of August
Sardonyx is the original August birthstone, with a history that dates back more than 4000 years.
Definition:

The History of Sardonyx:
In ancient times, sardonyx was a popular stone for Roman seals and signet rings, as hot wax would not stick to it. For millennia, the bands of color in this August birthstone have made it a popular carving material for cameos and intaglios.
Sardonyx is believed to be one of the stones in the High Priest’s breastplate, as referred to in the Old Testament, and to represent the strength of spiritual life.
Roman soldiers wore sardonyx rings with the image of Mars carved on them for protection in battle.

Care & Cleaning:
Sardonyx is 6.5 to 7 on the Mohs scale of Harness. As with Peridot, care should be taken when wearing it, especially as a ring. Note that Sardonyx, like other forms of Chalcedony, is commonly dyed. High heat, as in jewelry manufacturing or repair techniques, might affect the color of dyed Sardonyx. Ultrasonic and steam cleaners should be used with caution. Again, warm, soapy water applied with a soft-bristle brush is the safest option.
