Crafted in 14K yellow gold, this Croft & Stern original design features a 1.91ct bezel-set Australian Andamooka opal paired with a 0.29ct bezel-set round lavender spinel. Suspended from a 0.80mm round wheat chain adjustable to 16", 17", or 18", secured with a lobster clasp and finished in a bright polish.
Collector’s note:
Andamooka opals, mined in South Australia’s arid outback, are renowned not only for their vivid play-of-color and unique patterns but also for their low water content, typically around 3–6%. This makes them more stable and less prone to cracking or crazing compared to opals from wetter regions, allowing them to retain their beauty over time. Producing both crystal opals, with their translucent brilliance, and matrix opals, with intricate earthy patterns, Andamooka opals are highly sought after by collectors and jewelers alike. Their rarity and durability, combined with historical prestige—such as the 203-carat opal presented to Queen Elizabeth II in 1954—cement their status as exceptional gemstones.
