Black Onyx Spinning Cube
This polished black onyx cube, about 5cm, spins on a base and is engraved with "Yes" and "No" for a playful way to ask a question. Black onyx is a chalcedony/quartz variety commonly dyed to deepen its color, and this cube is flecked with natural pyrite for a bit of sparkle. Made in Peru, it doubles as a tactile fidget piece and a desk conversation starter.

Meaning & history

How to use it
Spin the cube on its base and let it land on "Yes" or "No" for a fun, low-stakes way to weigh a small decision, or simply keep it on a desk as a fidget piece. Treat it as a playful novelty rather than a serious decision-making tool.
Care & cleansing
Important: the pyrite flecks in this cube can rust or oxidize if exposed to water, humidity, or salt, so keep it dry at all times. Because the onyx is commonly dyed, avoid soaking or harsh chemical cleaners, which can fade the color; a soft, dry cloth is the safest way to keep it looking its best.
