“I love the way onyx absorbs light and has almost a  matte-like appearance. Black onyx has a vintage feel. It was popular in antique rings and I love incorporating it in a fresh way!”

- Jillian Sassone, Creative Director & Founder

The Black Onyx ring collection has quickly become a fan favorite— the designs allow for individual clients to show off their unique sense of style. 

Why We Love Black Onyx

Did you know Black onyx is known as the warrior stone? This stone also carries some other unique traditions: Black onyx has been said to absorb and transform negative energy and help prevent the drain of personal energy. 

Starting at $1300

Besides the metaphysical properties, black onyx just looks cool. It's unexpected & modern (despite being used for decades in jewelry design)—we also love the pricepoint. For our brides who are looking for something their friends won't have and are also keeping their budget in mind, black onyx can be the perfect stone.

How to Care for Black Onyx

Black onyx is a variety of the silica mineral Chalcedony, and it is a 6.5-7 on the Moh’s scale, which means it is a pretty soft stone when compared to a diamond, so you want to be gentle with it. 

That means no super physical activity or doing the dishes in your ring. We also recommend avoiding any harsh chemicals such as cleaning supplies and chlorine from a pool. 

If you need to give your Black Onyx ring a good scrub, use warm soapy water and a soft toothbrush and remember to be very gentle with it. 

Styling Black Onyx Designs

Stack 'em up

When designed our onyx pieces, we took the stacking capabilities to the next level. Into open shank concepts? They'll look fantastic. Prefer an art deco vibe? Our art deco bands work perfectly.

Since these pieces are super-stackable, you can create a one-of-a-kind ring look and even mix up your stackers for new looks daily.
