What Onyx means

Roman engravers cut banded onyx into seals and cameos, carving through a pale layer so a portrait stood out against the dark one beneath. It holds resolve the same way, one clean edge kept against whatever tries to blur it.

Emotional properties

A cutting remark lands and wants an equally sharp reply, and onyx asks you to wait one full breath before giving it one. Its flat black gives nothing away, no flicker of temper for anyone else to read. Slip a piece into a pocket on a day full of people trying to provoke a reaction, and let your face stay as unreadable as the stone does. The reply you give an hour later is usually the better one.

Spiritual properties

Most black onyx on a shop shelf has been dyed to an even, uniform black, since stone this consistently dark rarely forms on its own. The dyed and the true look alike on a shelf, and it takes a steady look to tell them apart, in a mineral and in yourself. Ask, in meditation, which parts of your composure are genuine and which are only put on for the room. The honest answer rarely arrives as fast as the question.

Physical properties

Onyx polishes to a black mirror, deep enough to show a face in it. Rest a flat piece under the writing hand before something that needs a steady grip, signing a document, threading a needle, holding a pose without a wobble. Its weight does not shift or roll, and neither does the hand resting on it.

Care and cleansing

Most black onyx is chalcedony soaked in sugar and then acid, which sets a stable black, though onyx dyed blue or green can fade in strong sun. Cleanse it at the tap, charge it overnight on a bed of quartz, and let it share a drawer with agates, which are just as hard.

A question to sit with

Before you answer the next sharp remark, what would one full breath change?
