Interesting Scientific Facts

Black onyx is a variety of chalcedony, a form of microcrystalline quartz—meaning it’s made of tiny quartz crystals too small to see without magnification.

Its deep colour often comes from natural carbon or iron inclusions, as well as geological processes of heat and pressure within the Earth’s crust.

Onyx forms in parallel banded layers, though black varieties often show subtle or hidden banding.

With a hardness of 6.5–7 on the Mohs scale, it is durable and well-suited for everyday handling, carving, or jewellery.

Historically, onyx was used by ancient Romans for engraved seals, because wax doesn’t stick easily to it.
