Opal Care

So you have just spent a significant amount of money on your Opals and now you want to know how to care for them. Here are some handy tips, broken down by specific questions, that will keep your Opal bright for a lifetime.

Can I put my opals in water?

Yes, there is no problem in doing this. But if the stone were an opal doublet or opal triplet it would be unwise to leave it in water, particularly hot water with detergent. In the case of solid opals, hot water or detergent or oils will not affect them.

How do oily substances affect an opal?

Oily hand and face creams will not hurt the stone, except that it may build up around a ring and make it look unsightly. The oil won't soak into the stone or hurt it in any way, but grime and the possibility of scratching would be the biggest problem.

What should I do to avoid damaging an opal?

Don't wear it doing the gardening, because the sand or soil may take the polish off the stone. Take it off if you are doing any sort of work that could bring the stone in contact with hard surfaces. A flick of the wrist in the wrong direction could chip it.

What do I do if my stone loses its polish or becomes scratched?

If opal is scratched after a few years it can be re-polished by most jewelers or a polisher at a lapidary club.

How do I store my opals for long periods of time?

Generally it's safe to store them away, as long as the area is not overheated. It's not a bad idea to put them in a sealed plastic bag with a damp cloth in case of drying out. Don't store them for long periods of time under hot lights.
