Boulder Opal "Sea & Night Sky" Gold Brooch Circa 2000s

About the Item

This unique, spectacular triangular brooch is set with one freeform solid Queensland boulder opal flat cabochon with two distinct bands of colour representing the nights sky and the sea. The opal is surrounded by a yellow gold custom mounting reminiscing an ‘arts and crafts’ design. Secured with a metal pin and hook catch. Gemstone: One triangular freeform solid boulder opal flat cabochon (32mm x 28mm x 5.5mm) with two distinct bands of colour including a brilliant green/orange/mauve broad flash and patches of full spectral auras against a dark grey background, estimated weight 27.00cts Metal: 18k yellow gold Weight: 16.14 grams Measurements: length 4.8cm, width 3.3cm Era: Late 20th Century Circa 2000 Queensland Boulder Opal is celebrated not only for its visual appeal but also for its connection to the Australian Outback and the unique geological processes that give rise to this beautiful gemstone. They have a vibrant and captivating play-of-colours within. The colours can include a wide range of hues such as blues, greens, reds, and purples, and they can change as you view the opal from different angles. Unlike other opals that are typically cut as cabochons to showcase the entire gem, Boulder Opal is often left with its natural ironstone matrix as part of the finished piece. This matrix provides a unique and earthy contrast to the opal’s colours, making each piece truly one of a kind.
