1.84 Ct. Boulder Opal from Australia

This 1.84 carat fancy shape multi color opal is a Boulder Opal, originating from Australia, with dimensions of 11.27 by 7.38 by 3.41 mm. The gem has been fashioned into a tablet cut, offering a broad, flat surface that displays intense color intensity across its face, and it carries an excellent polish that enhances the play of color and minimizes surface abrasions. The stone is an assembly enhanced as a doublet, which means a thin slice of natural opal has been securely bonded to a backing material to stabilize the opal and to enhance its visual depth. The combination of the tablet cut, precise polish, and thoughtful assembly produces a visually striking gem that is suitable for a range of jewelry applications where appearance and stability are both important.

In terms of durability, a Boulder Opal doublet benefits significantly from its ironstone or engineered backing, which improves the gem's resistance to flexural stress and reduces the likelihood of fracture when compared with unsupported thin opal slices. Natural opal materials typically register in the range of 5.5 to 6.5 on the Mohs hardness scale, and they have lower toughness relative to many common jewelry gems. The backing used in this doublet compensates for that inherent fragility by providing structural support, making the stone more suitable for daily wear in rings, bracelets, earrings, and pendants when set responsibly. The tablet cut further contributes to wearability by presenting a stable, low profile that is less likely to catch on clothing and is more amenable to protective settings.

To ensure reliable daily wear performance, consideration of setting and routine care is important. A bezel setting or a protective halo and flush mount for fingers will shield the broad table and edges from direct impact, while secure prong placements can anchor the stone with minimal exposure. Avoiding ultrasonic cleaners and steam cleaning is recommended for any doublet, because the adhesive layer can be vulnerable to heat and aggressive vibration. Prolonged immersion in water or exposure to solvents can also compromise the bond over extended periods, so routine hand washing is acceptable if drying is prompt, but extended soaking or chemical exposure should be avoided. Thermal shock is a concern for opal, therefore sudden, extreme temperature changes should be prevented. Periodic inspection by a qualified jeweler is advisable to confirm the integrity of the mounting and the bond.

The Natural Gemstone Company discloses the doublet enhancement and the Australian origin, and we provide accurate specifications to support informed purchase and care decisions. The combination of a quality tablet cut, excellent polish, intense play of color, and the structural support inherent in a Boulder Opal doublet makes this gem a practical and attractive choice for daily wear, provided that protective setting choices and reasonable care are observed. Routine maintenance, sensible wear habits, and professional inspection will sustain the opal’s appearance and structural integrity over the long term.
