Banded Black Onyx Pendant | 25mm Square | Sterling Silver

Our boldest black onyx pendant: a 25mm square of banded onyx in a sterling silver frame. Fine white lines of chalcedony run across the stone, giving it a graphic, almost architectural look.

Pendant details

•     Stone: banded black onyx cabochon, 25mm x 25mm

•     Setting: 925 sterling silver bezel

•     Free 18" sterling silver chain included – longer chains also available

Art Deco roots

Black onyx was a favourite of 1920s Art Deco jewellers, who paired it with silver and platinum in strong geometric shapes. This square pendant follows the same monochrome idea.

Geology in brief

•     Onyx is banded chalcedony – microcrystalline quartz

•     Hardness of 6.5–7, so it resists everyday knocks

•     The banding in every stone is unique

Gifting and meaning

An alternative July birthstone, the zodiac stone for Leo and the traditional 7th wedding anniversary gemstone. Onyx is said to promote focus and resilience – a good gift for someone starting something new. See our black onyx birthstone guide.

How to wear it

A square this size looks best sitting lower, so try it on a 20" or 24" chain over a plain top or shirt dress.
