Black Onyx Pendant | 20mm Oval Gemstone | Sterling Silver

A smooth, jet-black oval of onyx in a clean sterling silver bezel – the kind of pendant you put on in the morning and forget to take off. At 20mm x 15mm it is noticeable without being loud, and the deep black gives a sharp contrast against a crisp white shirt.

Pendant details

•     Gemstone: polished black onyx cabochon

•     Stone size: 20mm x 15mm oval

•     Setting: 925 sterling silver bezel and bail

•     Free 18" sterling silver chain included

A stone with an ancient name

Onyx takes its name from the Greek onux, meaning fingernail. It is a form of chalcedony, a microcrystalline quartz rating 6.5–7 on the Mohs scale, so it copes well with daily wear.

Meaning and gifting

•     Alternative July birthstone (alongside ruby) and the zodiac stone for Leo

•     Traditional gemstone for a 7th wedding anniversary

•     Valued as a grounding, protective stone said to absorb negative energy

•     Suits minimalists who want jewellery that goes with everything

How to wear it

Wear it short on the 18" chain with an open collar, or over a fine-knit jumper. Read more in our guide to black onyx as a birthstone.
