The Story of Onyx
Onyx comes from the Greek onyx meaning fingernail or claw — ancient Greeks thought the stone, with its translucent layers, resembled a human fingernail. It is a variety of chalcedony quartz typically characterized by parallel bands of black and white. The Romans used onyx extensively for cameo jewelry, carving images into its contrasting layers. As a given name, Onyx belongs to the growing trend of gemstone names for babies (Jasper, Jade, Ruby, Opal, Garnet).
Onyx as a given name has been gradually rising in the US since the 2010s, as parents seek names that are distinctive, nature-connected, and have an edge to them. It fits the broader gemstone-name trend while leaning more masculine than Ruby or Opal due to its hard consonants.
Onyx has been used in jewelry and art for millennia — prized in ancient Egypt, Greece, and Rome. In many traditions, onyx is associated with protection, strength, and grounding energy. The stone was thought to absorb negative energy and give its wearer courage.
