Ask a careful dealer about white agate and you will hear that it is usually left as it was found, with little done beyond cutting and polishing. That is normal for the family; it is not a promise about any single stone, and a sensible buyer still asks.

So please ask about this one. This 21.30 carat white agate carries the reference AG-WH-0004. Message us on WhatsApp and we will tell you what we know. If you would like something on paper, independent lab testing is your choice.

What we can say now is simple. It is a natural white agate of 21.3 carats, rated 6.5 to 7 on the Mohs scale. At this weight it makes a good broad silver ring for a man, or a pendant with presence.

Keep it away from harder stones in storage and wipe it with a soft damp cloth. A pale stone shows dirt and soap film more than a dark one, so a quick clean now and then keeps it looking its best.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

On the Mohs scale white 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 white 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.
