3.50 Ct.Tw.Total Carat Weight Cabochon Opal Pair from Australia

This pair of White Opal cabochons from The Natural Gemstone Company consists of one stone weighing 1.84 carats and the companion weighing 1.66 carats, each presented in an oval shape, with dimensions of 10.25 x 8.18 x 3.43 millimeters for the larger stone, and 10.23 x 8.11 x 3.23 millimeters for the smaller stone, both stones are translucent with a multi color play of light, the finish is cabochon cut with an excellent polish, the clarity grade is eye clean as evaluated at eye level, the color intensity is classified as medium, there are no enhancements, and the documented origin is Australia. These are White Opal specimens, characterized by a light body tone that provides a soft, luminous background for flashes of spectral color, and the close correspondence in dimensions, shape, and polish renders this pair well matched for use as a matched set for earrings or for a coordinated pendant and ring combination. The cabochon form enhances the play of color, allowing the diffraction of light within the microstructure of silica spheres to present dynamic flashes of green, blue, and subtle red, and the excellent polish maximizes luster and visual depth while the eye clean clarity ensures these flashes are not interrupted by visible inclusions.

From a gemological perspective, the clarity grade of eye clean indicates that inclusions or internal features are not detectable to the unaided eye at normal viewing distances, which is particularly desirable in opal because surface and internal features can affect the transmission and scattering of light that produce the play of color. The medium color intensity designation describes the saturation of the opal body color and the strength of the play of color, meaning these stones exhibit pleasing and noticeable color flashes without the deep body tones found in black opal or the extreme vividness of rare specimens, this balance often appeals to buyers seeking wearable, versatile stones. The cabochon cut is the traditional and most effective cut for opals because it preserves thickness to protect the stone, and it presents the color play across a domed surface that shifts with movement, the relatively modest depths of 3.43 and 3.23 millimeters are appropriate for secure mounting while maintaining a comfortable profile for jewelry, and the pair is sufficiently matched that lapidary symmetry will allow for balanced settings.

For the educated buyer, the value proposition of this matched pair is grounded in several verifiable attributes, the stones are natural, untreated, with no enhancements, and they originate from Australia, a source with a long established reputation for producing stable, well formed opal specimens with consistent body tone and play of color, in contrast to hydrophane opals from other localities which may absorb liquids and change appearance, Australian white opals typically offer stable clarity and color response when set and worn. The play of color, even at medium intensity, is important because it is the defining aesthetic quality of opal and is what collectors and designers prize, combined with eye clean clarity and an excellent polish this pair offers both visual appeal and practical ease of setting, matched pairs in closely similar carat weight and dimensions command a premium among designers because they reduce the need for additional cutting and matching, and when set in quality mountings their visual impact and perceived value increase, buyers who prioritize provenance, documented origin, and lack of enhancement will find these stones aligned with conservative investment preferences, The Natural Gemstone Company stands behind provenance information and can assist in obtaining independent documentation if required.

In terms of care, handling, and recommendations for setting, note that opal has a Mohs hardness that averages between 5.5 and 6.5, which makes it softer than gemstones such as sapphire or diamond and more susceptible to abrasion and impact, it is advisable to select protective settings such as bezel or semi bezel settings for rings, or to set the pair as earrings or pendants where the risk of direct abrasion is lower, avoid exposure to harsh chemicals, prolonged immersion in liquids that are not advised for hydrophane specimens, and sudden temperature shocks which can cause crazing in some opals, cleaning is best accomplished with a soft cloth and warm soapy water, ultrasonic and steam cleaning should be avoided as a precaution, because these stones are Australian White Opal, they are less prone to water absorption than some other opal types, yet care should still be taken when cleaning and wearing. If you would like a written appraisal, custom mounting, or assistance selecting complementary gemstones or metals for a setting, The Natural Gemstone Company can provide expert guidance, bespoke mounting services, and recommendations for independent laboratory reports to support insurance and resale, please contact us for detailed photographs, certificates, or to discuss mounting options that will both protect and showcase the intrinsic play of color these matched White Opals have to offer.
