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. These rings also make the perfect right-hand ring and they are super stackable! 

From the designer, Jillian Sassone: “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!”

Why We Love Black Onyx 

Did you know Black onyx is known as the warrior stone? This stone is so special and unique for a couple of reasons: 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! 

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. 

We recommend taking your black onyx ring off for any kind of physical activity and avoid any harsh chemicals such as cleaning supplies and chlorine from a pool. To clean your black onyx ring, use warm soapy water and a soft toothbrush and remember to be very gentle with it. 

The Black Onyx Capsule

Our 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 these alternative wedding rings, we decided to expand on our black onyx ring capsule for our edgier brides and at a more affordable price point. Plus, we made all of the new black onyx rings super stackable! 

The Rhiannon Round Black Onyx Solitaire

This simple yet stunning design looks amazing with two Gemma Ballerina Ringsaround her! This super stackable black onyx solitaire ring also pairs perfectly with the Courtney Mixed Shape Jacket.

The Bewitched Black Onyx 3 Stone Ring 

If a three-stone ring is more your style, we love how she looks stacked with a Simple Wave White Diamond Band and our Gentle Curve Chain Ring for an edgier look. This black onyx ring also looks gorgeous with our Round and Pear Ballerina Jacket which features .30 carats of white diamond baguettes!

The Paint It Black Perfect Halo Ring

Subtle yet eye-catching, this microhalo design adds some black diamond sparkle that we’re obsessed with. We suggest going big with stacking this marquise-shaped ring and pairing her with Black Diamond Headdress Jacket! She also looks amazing with the Seven Stars Nesting Ring if you want something a little more subtle.
