Sardonyx is a variety of Onyx that contains bands of Carnelian.
The name comes from the Greek words for reddish-brown and nail or claw, referring to its reddish-brown base colour and white or black bands. It has been used for centuries in jewellery and decorative objects due to its beauty and durability.
Sardonyx is associated with courage, happiness, and clear communication, and is considered a stone of strength and protection.
