Introducing "Heart of Atlantis,"

A 1980s 18k Gold & Diamond Modernist Pendant Featuring a Blinding Green, Collector-Grade Boulder Opal with Non-Directional Fire

Crafted from solid 18k yellow gold, this 1980s-era pendant was acquired from a Beverly Hills estate and features a collector-grade Australian boulder opal.  Weighing over 10 grams and measuring a substantial 1.6” long, the Modernist architecture achieves a surprisingly elegant aesthetic given its statement-worthy size.  The pendant is engineered with a sturdy clip-on enhancer bail that integrates seamlessly with the overall design, allowing the piece to be securely affixed over thick chains, gold omegas, or heavy pearl strands.  Two tube-set VS2-clarity diamonds (0.07ctw) accent the opal.

The architectural centerpiece is a massive, freeform boulder opal sourced from Queensland, Australia.  Defying standard photographic capture, the B5-rated intense green play of color exhibits true non-directional fire, leaping from the stone’s dark N5 body tone at every viewing angle.  Enchanting layers of deep blue and purple play beneath the dominant green surface, providing a three-dimensional depth rarely found in standard boulder opal specimens.

Measuring approximately 1.1” long as set, the opal exhibits a highly coveted “clean face”—meaning no ironstone inclusions interrupt the flow of precious opal across the stone’s primary viewing surface.  Unlike man-assembled imitations, this is a solid, natural stone; the seam of precious opal formed organically over its host ironstone matrix, clearly visible in the profile gallery images.

Whether acquired for investment or wear, this piece is a true gemological marvel.  A complimentary 18” gold-plated sterling silver rope chain is included so the pendant can be worn immediately upon arrival.

For collectors seeking a similar aesthetic in a more understated scale, explore our Atlantic Sunrise Modernist-style Australian boulder opal and diamond pendant, which features a flatter profile and a wider spectrum of visible color play.
