A stone rated 6.5 to 7 on the Mohs scale is a sturdy one. Quartz, the mineral at the heart of agate, is harder than steel, so everyday dust will not scratch it. What it fears is a hard blow on an edge. In a ring, set it in a bezel and take it off for the gym or manual work. In a pendant it will last almost indefinitely.

This 17.75 carat natural green agate is a large, substantial piece, a natural fit for a broad gents' ring in silver.

The colour is the deep green people look for in Sabz Aqeeq, and green of that strength is usually dyed. Ask us about this stone on WhatsApp, quoting AG-GR-0007, and we will tell you what we know.

For care, wash it in lukewarm water with a drop of mild soap and a soft brush, then dry it with a cloth. Avoid ultrasonic cleaners and hot water, as dyed stones can be sensitive to heat. Store it in a pouch away from harder gems.

On the Mohs scale green 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.
