Black agate, kala aqeeq, is a stone people wear without thinking twice, and at 6.5 to 7 on the Mohs scale it earns that confidence. It is harder than a steel knife blade, so everyday knocks rarely leave a mark. Rings and bracelets are well within its comfort zone; just keep it apart from sapphire, ruby and topaz in a pouch, since those can scratch it.

Cleaning is simple: warm water, a drop of mild soap and a soft cloth. Avoid long soaks and strong solvents.

On the Mohs scale black agate rates 6.5 to 7. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.
