Frequently asked questions
Is black onyx a real natural stone?
Yes — black onyx is a variety of calcite or banded agate, extracted naturally. Its deep black color is natural or slightly enhanced by dyeing — a common and accepted practice in jewelry. Beware of glass or resin imitations: the real stone is cool to the touch and slightly heavy.
What is the difference between black onyx and obsidian?
Black onyx is an agate with a crystalline structure, opaque and of a uniform deep black. Obsidian is a natural volcanic glass, often with pearly or golden sheen. Onyx is generally harder and more resistant. Both are used in jewelry for their dark elegance, but their energetic properties differ.
Is black onyx suitable for men?
Absolutely — black onyx is one of the most worn stones by men in jewelry. Its dark color and assertive presence go perfectly with masculine signet rings and bracelets. It is the ideal stone for a first men's piece of jewelry or to ground a dark-luxe look.
How do I care for black onyx jewelry?
Clean with lukewarm soapy water and a soft cloth. Avoid ultrasonic cleaners and chemicals that can alter the surface of the stone. Store separately to prevent scratches. Onyx is a relatively resistant stone (hardness of 6.5-7 on the Mohs scale) — it holds up well to daily wear.
