2.95 Ct. Multi Color White Opal (Light Opal) from Australia

This specimen is a 2.95 carat, oval shaped White Opal, light opal, measuring 14.48 x 11.54 x 2.93 millimeters, sourced from Australia and presented by The Natural Gemstone Company. The cutting style is tablet, producing a low domed profile with a broad, polished surface that emphasizes the stone surface interplay and maximizes visible play of color at moderate viewing angles. The piece is translucent with multi color play dominated by blue and green flashes and subtle secondary hues, and the overall color intensity is graded as medium. Clarity is graded eye clean when evaluated at normal viewing distance, there are no visible inclusions or surface reaching fissures, and the finish has an excellent polish that enhances the stone luster without masking internal optical phenomena. There has been no enhancement to this opal, it is a natural solid material rather than a doublet or triplet, and the tablet cut preserves material integrity while delivering a wide, even surface for light capture.

From a lapidary perspective the tablet cutting approach used here prioritizes a shallow crown and broad table, optimizing the diffractive response of the internal silica sphere lattice that produces the opal play of color. The relatively thin profile at just under three millimeters requires precise control of table flatness and crown curvature to avoid windowing or dead zones where play of color may be diminished. In this specimen the cutter established a controlled convexity across the oval table, producing consistent color distribution across the face while maintaining edge uniformity for secure setting. The medium color intensity indicates a balanced concentration of color bearing zones, manifesting as dynamic broad flashes and patches rather than tightly concentrated pinfire. Predominantly green and blue spectral components are present, these correspond to silica sphere arrangements that diffract shorter wavelengths more efficiently in the observed orientation, while the translucent body allows for depth and layered color effects when viewed at oblique angles.

Craftsmanship details include a well centered oval outline with symmetrical axis proportions, a smooth girdle rim consistent with tablet cutting protocols, and an excellent polished finish free of abrasion marks or polishing laps. The tablet cut reduces overall height and shifts emphasis to surface color play, therefore the gem is ideally suited to settings that maintain low profile and protect the thin edge. For jewelry applications we recommend secure bezel mounting with a narrow but protective metal rim that overlaps the girdle enough to resist lateral force, or a low profile flush setting for inlay work where the tablet form sits nearly level with the metal plane. High prong settings are less advisable for a sub three millimeter thickness, unless prong geometry is engineered to support both the table and girdle without inducing stress. When setting, leave a small clearance for thermal expansion and avoid bonding agents that may trap moisture against the stone surface. The stone is stable under normal wearing conditions, however opal is sensitive to abrupt temperature changes and prolonged exposure to harsh solvents and ultrasonic cleaners, therefore mechanical cleaning with a soft cloth and mild soapy water is the preferred maintenance method.

For the technically minded buyer this White Opal, light opal, represents a combination of desirable control in cut, natural Australian provenance, and unenhanced material quality. The eye clean clarity and excellent polish indicate careful pre and post cut handling and make this gem suitable for collectors and craftsmen who require predictable optical behavior for design planning. The tablet cut yields a strong surface oriented play of color that photographs and displays well in shallow settings, and the measured dimensions allow for precise calibration into custom mountings with minimal adjustment. The Natural Gemstone Company endorses full disclosure on origin and treatment status, and this stone is offered as a natural, untreated Australian white opal with documented weight and dimensions. If independent laboratory verification or additional facet orientation imaging is required for appraisal or design integration, such services can be provided, and our team can advise on optimal mounting techniques to preserve color response and long term stability.
