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

This entry from The Natural Gemstone Company is a finely executed White Opal, Light Opal, weighing 1.84 carats. The piece is presented in a round outline with measured dimensions of 10.16 x 10.14 x 2.97 mm, and a tablet cutting style that prioritizes surface display over depth. The tablet cut produces a broad, shallow profile that maximizes the visible play of color when viewed face up, while maintaining a controlled thickness of 2.97 mm to balance durability and optical performance. Weight to size ratio is consistent with hydrated silica material, and the documented carat weight reflects precise trimming and removal of non optic host material during preform. This opal is translucent, with a light body tone that allows a full spectrum of spectral color to emerge. The origin is Australia, a benchmark locality for White Opal, Light Opal specimens, and no enhancement has been applied, confirming that the play of color and surface condition are wholly natural.

The tablet cut applied to this gem is a specialist variant of cabochon shaping intended to emphasize broad flash and mosaic patterns rather than faceted scintillation. During cutting the lapidary would have preformed the round pavilion and then flattened the dome slightly to create a tablet profile, refining the edges to a consistent girdle circumference near 10.16 mm. Polishing was carried out to an excellent finish, achieving a smooth optical interface that minimizes internal scattering from surface irregularities. The polish quality is especially important for opal, where even minor abrasions can diffuse the internally generated color and reduce intensity. The cutter has preserved an optimal table plane to allow directional viewing across multiple angles, and the shallow depth enhances face up color at common wear orientations. This approach is highly regarded by connoisseurs who value expansive color fields and predictable orientation in wearable designs.

Optically the gem exhibits intense color intensity with multi color play distributed across the tablet surface. The patterning is broad and appears as interlocking patches of red, green, blue, and orange, suggesting well developed silica sphere layering that produces strong diffraction across visible wavelengths. Clarity is graded as eye clean at standard eye level evaluation, indicating absence of significant inclusions or fractures visible without magnification, and confirming structural integrity for setting. The translucency permits some light transmission, which can enhance internal color shift under variable lighting, and the light body tone contributes to a luminous backdrop that amplifies pastel hues as well as saturated flashes. Refractive index in opals is characteristically low, typically around 1.44 to 1.46, and the specific gravity for solid opal materials is approximately 2.1 to 2.2, values that are consistent with the observed heft and handling of this 1.84 carat tablet. The combination of intense color intensity, eye clean clarity, and excellent polish elevates the stone to a collector grade within the category of White Opal, Light Opal specimens.

For practical considerations and provenance, this tablet cut white opal is offered with full disclosure that no treatments or stabilizations have been applied, preserving original material properties. The Australian origin is noted for its characteristic interplay between soft body tone and vibrant color flashes, making it suitable for a variety of mounting strategies. Recommended settings include low bezel or flush mountings that expose the tablet face to light, or a raised bezel with a thin profile that does not obstruct the table plane. Ring settings should account for the moderate surface hardness of opal, typically Mohs five and a half to six and a half, so protective design elements are advisable for daily wear. Care instructions include avoidance of rapid thermal changes and harsh chemicals, and cleaning with mild soap and water using a soft cloth.
