Sleek, powerful, and grounding, black onyx has been a stone of strength and protection for thousands of years. Its deep black color represents the kind of quiet, steady power that gets you through hard times.
Here's what black onyx represents and why it's such a meaningful stone.
WHAT IS BLACK ONYX?
Black onyx is a variety of chalcedony with parallel bands of color. While naturally banded onyx exists, most black onyx is actually chalcedony that's been treated to achieve its uniform deep black color.
The name comes from the Greek word for "claw" or "fingernail" — legend says the stone was formed from the clipped fingernails of Venus. Black onyx is associated with the zodiac sign Leo.

WHY CHOOSE NAVY GEMS?
The meaning behind a crystal only matters if the person receiving it knows why you chose it for them. That's where most crystal jewelry falls short — it's beautiful, but the intention gets lost.
Every Navy Gems piece comes with a meaning card that explains the stone's symbolism and why it was chosen. It transforms a pretty necklace into an intentional, meaningful gift — one where the receiver understands exactly what you're saying without you having to find the words.
It's not just jewelry. It's a message.
