Nearly nineteen carats of green agate gives a jeweller plenty to work with, and there are a few sensible routes.

A broad ring. This is the classic home for a stone of this scale. Set it in a heavy silver bezel so the metal wraps the edges. At 6.5 to 7 on the Mohs scale it is tough enough for regular wear, and the bezel guards against knocks.

A pendant. Here the weight sits quietly on the chest, and nothing rubs against it all day. A good choice if you worry about scratches.

Something bespoke. A custom silver ring setting can be discussed with us on WhatsApp +92 308 887 3888; just share the reference GS-GR-0008 and what you have in mind.

About the stone itself: it is a natural green agate of 18.95 carats, priced at Rs. 2,840, about Rs. 150 per carat. Deep green agate is usually dyed, so ask us what we know about this piece. Others in the family can be browsed under green agate.

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.

Whoever you buy green agate from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone.
