Alternative Gemstones: All About Black Onyx

Alternative Gemstones: All About Black Onyx

 Here at Marrow, it's no secret that we love an alternative engagement ring! Our newest collection of black onyx rings is just that—the perfect engagement rings for our edgy brides. Even if you aren’t engaged, the collection makes a perfect addition to any ring finger. 

 When crafting the new gem collection, designer Jillian Sassone said: “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!”

The Black Onyx ring collection has quickly become a fan favorite here at Marrow Fine and we think it is the perfect piece to show off your unique sense of style! 


Why We Love Black Onyx  

Did you know Black onyx is known as the warrior stone? Who doesn’t love a little “boss babe” vibe sitting right on your finger. 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. 

Black onyx is also known to inspire personal power from facing your fears and it symbolizes initiation and change within oneself. This moody stone can also help clear your mind of self-doubt and societal expectations leaving just your authentic self to tackle the world! 

So, it was no surprise when the team here at Marrow Fine chose this alternative gem for an engagement ring collection. Every woman wants to feel empowered and radiate positive energy in their marriage. Also, if you decide to wear the Black Onyx ring outside of an engagement ring, it brings you some amazing vibes that you just can’t pass up. 

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. Plus, the Marrow Fine team recommends 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. 

About The Black Onyx Capsule

At Marrow Fine, the Sweet Melissa Black Onyx Ring is one of our most popular rings and we can see why! This pear-shaped black onyx is absolutely stunning with the white diamonds down the shank—a little brighter sparkle next to the deeper color of black onyx. Since she is so popular, we made a mini version of her and our Marrow babes have loved that design too!


With such good reception to the Black Onyx rings being used as  alternative wedding rings, we decided to expand on our  black onyx ring capsule for our edgier brides and at a more affordable price point. 

The ring capsule is also designed for every edgy lady out there, not just our brides. The Black Onyx is perfect for any occasion and we made them all super stackable to go with all of your existing rings.
