Crafted in 18K white gold and 14K yellow gold, this Croft & Stern original design features a 9.17ct bezel-set Andamooka opal cut by Paul Christiansen. Accented by a bezel-set 1.47ct round Brazilian chrysoberyl. Suspended from a gold-tone and stainless steel 7-strand collar, 20" length, secured with a bayonet clasp. Finished with a bright polish.
Collector’s note:
Andamooka Opal: 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.
Chrysoberyl: Chrysoberyl is one of those gemstones serious collectors pay attention to—quietly rare, historically respected, and completely misunderstood by most casual buyers. Long before modern gem fads, chrysoberyl was prized for its hardness (8.5 on the Mohs scale—just under sapphire) and its unmistakable presence in three distinct varieties: traditional yellow-green chrysoberyl, the luminous cat’s-eye, and the elusive color-changing Alexandrite.
