Some opals are quiet and some are loud, and the only way to know which you are dealing with is to see the colour move. This 2.55 carat stone is a natural fire opal from Australia with play-of-colour, and the flashes are the whole point of buying it.

The price is Rs. 21,380, about Rs. 8,384 per carat. The reference is GS-000608.

Because opal is soft, at 5.5 to 6.5 on Mohs, the best use for a stone this size is a pendant, or a ring worn on the less active hand for special days. Avoid hot water, steam, ultrasonic cleaners and sudden temperature changes, all of which can stress opal. A soft damp cloth is enough for cleaning.

A short note on treatment: whole opal is mostly left as found, but darkened opal exists, and doublets and triplets are common. We sell solid natural opal, and if you send us the reference on WhatsApp we will tell you what we know about this exact stone. Independent lab testing is available if you ask.
