Are your black onyx rings made from real onyx?

Our black onyx-style rings are not made from natural onyx. Instead, we use high-quality black cubic zirconia and matte finishes that replicate the appearance and elegance of onyx.

Can I wear a black onyx ring every day?

Yes. Our rings are made from waterproof, sweat-resistant, and hypoallergenic stainless steel, designed for daily wear — even while washing hands, exercising, or swimming.

Do your rings turn fingers green?

No. Our black onyx rings are crafted from nickel-free stainless steel with vacuum plating. They are safe for sensitive skin and do not discolor or stain fingers.

What does a black onyx ring symbolize?

Black onyx traditionally symbolizes strength, protection, and inner focus. Even our faux onyx rings carry this meaning, making them powerful statement pieces or meaningful gifts.

Are black rings in fashion?

Yes. Black rings are trending in 2025 for their minimalist design, unisex appeal, and bold look. They work well alone or layered for a modern statement.
