This item was received from someone else. It has a small "925" stamp. I'm decluttering, as I won't be using it. I believe it was a souvenir from Australia, famous for its opals, but I've forgotten the details. Those going to the Expo can wear it, or those not going can enjoy it while imagining Australia and enjoying the fashion. It has a tablet opal-like decoration. It appears to be a good quality item, made with solid silver 925. Tablet Opal
