"The opals are beautiful! What is particularly helpful is that as well as the very accurate descriptions and measurements, there are videos of each stone shown from different angles on the website, so you know exactly what the stone looks like (all the different flashes of colour and every little detail of the stone). Even the stones at lower price points are shown in detail. This means that one can buy these opals online with real confidence. William is extremely helpful with any queries. Everything arrives quickly and safely and is exactly as described. I cannot recommend this business highly enough!"

"I had an absolutely fantastic experience with W.M OPALS! The service was professional, friendly, and incredibly knowledgeable — you can tell they truly have a passion for opals. The opal I received is breathtaking — the colours and the quality are even better than I expected. Photos honestly don’t do it justice! Communication was excellent from start to finish, and my order arrived quickly and safely packaged. It’s clear that every piece is handled with care and expertise. I’ll definitely be coming back for more and recommending W.M OPALS to anyone looking for truly stunning, high-quality opals and expert service."
