1.70 Ct. Multi Color Crystal/Jelly Opal from Australia

This Crystal/Jelly Opal from Australia is a translucent, multi color specimen weighing 1.70 carat, presented in a freeform lozenge profile that measures 14.16 x 6.87 x 3.29 mm. The piece has been precision shaped and given a polished cut rather than faceting, a technique chosen to maximize its internal play of color while maintaining the stone's natural fluid outline. At a thickness of 3.29 mm the pavilion permits light transmission that enhances the crystal opal effect, creating a three dimensional color flash rather than surface only iridescence. Clarity is graded eye clean, evaluated at eye level, indicating an absence of visible inclusions or potch that could interrupt color flow. Color intensity is medium, with consistent multi spectral flashes distributed across the table and shoulders, and the polish quality is excellent, reflecting a final lapidary stage executed with fine abrasives and cerium oxide to an even high gloss. No enhancement has been applied, this opal is natural, untreated and not assembled as a doublet or triplet, which ensures stable optical behavior and long term integrity in a high quality setting.

The journey of this opal from mine to market embodies controlled selection and deliberate lapidary technique. Extracted in Australia, the rough was examined for color direction, thinness and fracture lines, then oriented to cut for maximum color yield while preserving weight. The preforming stage used diamond grinding wheels to establish the freeform geometry, followed by a graduated sanding sequence to remove sub surface stress and to shape the final dome and girdle with dimensional accuracy. Final polishing was executed to bring out the stone's internal play of color without over polishing that can reduce contrast in crystal types. At The Natural Gemstone Company each step is documented, including measurements in millimeters, carat weight, grade statements and photographic records for accurate reproduction. The result is a versatile freeform opal well suited to bezel or flush settings where its flat back and modest thickness provide secure mounting and optimal face up presentation. For connoisseurs who prioritize technical provenance, this Australian Crystal/Jelly Opal offers demonstrable craftsmanship, verifiable grading and a clean, untreated profile ready for bespoke jewelry implementation.
