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

So please ask about this one. This 21.30 carat white agate carries the reference GS-WH-0004. Message us on WhatsApp and we will tell you what we know about it, and independent lab testing is available on request if you would like paper.

What we can say now is simple. It is a natural white agate weighing 21.3 carats, rated 6.5 to 7 on the Mohs scale. The price is Rs. 3,200, about Rs. 150 per carat.

At this weight it makes a good broad ring in silver for a man, or a pendant of presence. Keep it away from harder stones in storage and wipe it with a soft damp cloth. Neighbouring pieces are grouped in white agate.

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.
