Onyx
AH-nihks
Onyx comes from the Greek onyx meaning “claw” or “fingernail.” The connection to the gemstone arose because the black and white banded stone was thought to resemble the layered appearance of a fingernail.
The gem has been used in jewellery and carving since antiquity.
As a given name, Onyx belongs to the gemstone-name tradition alongside Ruby, Jade, Jasper, and Flint. Its move to boys’ use reflects the broader trend of edgy, hard-sound gemstone names for boys.
What the name Onyx means
Onyx ranked No. 358 in 2024 with 927 births. It peaked at No. 307 in 2023 with 1,077 births, suggesting it is near its current high.
The name gained celebrity traction when rapper Tyga named his son King Cairo Stevenson Onyx in 2012.
Subsequently, other celebrities and social media personalities have used the name. The gem’s association with protection and strength in crystal culture also drives adoption.
Two syllables — ON-iks — are sharp and punchy. The hard x final consonant gives it a distinctive, edgy energy unlike softer gem names.
