We have a nice selection of Australian Opals available for sale here on St Claire Opals.
Peter Buchanan, who is Australian, obtains the beautiful opals from the finest of sources either from raw uncut stone or as an exquisite opal. He obtains the opals from various regions in Australia such as Lightning Ridge, which is also known as "Black Opals". Black Opals are highly sought after due to their brilliance in colour, especially when sunlight or light shines on them. Have a look at the wide range of such opals on the Opals link on the top menu.
Peter, the owner, and producer of many of the opals, cuts opals from the stone, works on and polishes them to the highest quality. He also attaches chains to some opals and he can add a silver chain if you prefer. He also has opals mounted on silver as a jewellery piece. Or, indeed, if you are a jeweller who requires the finest opals for your crafted jewellery, Peter would only be too happy to supply you with them.
