1.66 Ct. Multi Color Crystal Opal (Jelly Opal) from Australia

For more than a century gemstones have been the silent witnesses to personal stories and dynastic legacies, and this Crystal Opal, known as a Jelly Opal, arrives from that same timeless tradition. At 1.66 carats this oval gem carries a weight that immediately speaks to quality and presence, a size that balances wearable elegance with visible impact. We at The Natural Gemstone Company carefully selected this piece because its carat weight is not mere arithmetic, it is a measure of permanence and desirability. In the world of opals, a well-cut 1.66 carat stone offers an unmistakable face-up drama without becoming cumbersome, and collectors who prize proportion and longevity will recognize its premium stature. The dimensions, 10.07 by 7.93 by 5.57 millimeters, confirm a generous table and well-distributed depth, while the faceted mixed brilliant cut elevates the gem beyond conventional cabochon presentations to reveal flashes of multi-color scintillation with each turn and glance.

This Crystal Opal, Jelly Opal type, brings with it the soft, jelly-like translucence that has fascinated connoisseurs for generations, and its multi-color palette shifts gently beneath a medium color intensity that is pleasing to the eye and faithful to natural character. Faceted rather than left in the traditional smooth dome, this opal displays play-of-color with angular reflections created by the mixed brilliant cut, a cutting style that maximizes brilliance and introduces a modern clarity to an ancient material. Evaluated at eye level, the clarity grading is very slightly included, a trait that adds character without distracting from the gem’s luminous qualities, and the polish is excellent, producing a clean, satiny finish that enhances light performance. The opal has undergone heat treatment, a standard enhancement aimed at stabilizing and subtly intensifying color, and this disclosure is part of our commitment at The Natural Gemstone Company to full transparency regarding any treatments. Originating from Australia, a land synonymous with the finest opals, this stone carries geographic provenance that connects it to the long narrative of miners and lapidaries who have elevated opal to the status of national treasure.

To the collector, jewelry artist, or patron who values tradition and legacy, this opal is a modern heirloom, poised to be set in a ring, pendant, or bespoke creation that will be treasured across generations. The 1.66 carat weight translates into a tangible sense of value, a reassuring heft that preserves the stone’s presence in any design, while the oval outline is a classical silhouette favored through centuries of fine jewelry, ensuring that this gem will never feel out of place in a period piece or a contemporary setting. The mixed brilliant faceting invites creative settings that celebrate light, and settings that allow the opal room to breathe will best reveal its jelly-like translucency and the soft, shifting flashes of color. At The Natural Gemstone Company we encourage designs that respect the stone’s natural history, pairing it with warm metals that echo its internal fire or with simple, elegant mounts that let the 1.66 carat Crystal Opal speak for itself.
