About Us

Constable & Co Australian Opal Specialists

Based in Woodford and Winton Queensland we have close association to “Opalton”, the historic and most productive Boulder Opal field in Australia with a rich history of opal mining and some of the most spectacular opal stone ever discovered.

Constable and Co processes Queensland Boulder Opal from the rough form to fine Gemstones and are sold across the world as investment pieces or made into exquisite jewellery pieces.

The company originated as Colonial Opal, trading Opal, Pearl and Precious Gems starting in the early 1980s. We have a long proven history of Honesty, Integrity and Service in the supply of Australian Opal. Experience has been gathered in all levels and operations within the Opal Industry, starting in the wholesale and export gemstone and jewellery trade within Australia and Internationally, through owning and operating Opal specialist retail stores in Australia and New Zealand, all the while being involved in the mining, cutting and valuing of all varieties of Australian Opal. The company changed its name in 2018 to Constable and Co.
