2.74 Ct. Cabochon White Opal from Australia

The Natural Gemstone Company presents one translucent, multi color, White Opal weighing 2.74 carats, oval shape, with precise dimensions of 12.00 x 9.96 x 3.45 mm. This specimen is fashioned as a cabochon cut, exhibiting a smooth domed profile and a well balanced outline, with light color intensity that allows the internal play of color to register distinctly against a milky base. The opal shows flashes of green and blue across its surface, with occasional violet undertones, and the play of color is visible from multiple viewing angles, a characteristic that confirms its quality as a genuine Australian White Opal. The combination of translucency and subtle body tone provides a soft luminous backdrop for the color patches, and the overall presentation is consistent with high quality material suited for both display and fine jewelry applications.

Clarity is graded as very slightly included, evaluated at eye level, and these minor inclusions do not detract from the gem's visual appeal or structural integrity. The cabochon profile has been executed to achieve uniform thickness and symmetry, optimizing the interaction between incident light and the internal silica spheres that create the opal's diffraction effects. The polish is excellent, producing a clean, reflective surface that enhances the gem's luster without obscuring the internal color play. No enhancements have been applied to this opal, the material is completely natural, and its optical characteristics are intrinsic to the stone. The lack of treatment is an important attribute for collectors and designers who require untreated gemstones for accurate color matching and long term stability in finished pieces.

Origin is Australia, which is renowned for producing White Opal with reliable play of color and stable body tone. For setting and care considerations, this opal responds best to secure, protective settings that minimize exposure to hard knocks and sudden temperature changes, as opal is a hydrated amorphous form of silica with modest hardness relative to many gemstones. Routine maintenance involves gentle cleaning with a soft cloth and mild soap and water, avoiding ultrasonic cleaners and harsh chemicals. When set in rings, consideration for protective bezel settings or partial bezels is recommended to reduce edge exposure, while pendants and earrings benefit from more open settings that showcase the cabochon dome and allow light to interact with the play of color. This piece is offered by The Natural Gemstone Company as a well documented example of Australian White Opal, suitable for connoisseurs, designers, and discerning clients seeking natural, untreated material with an excellent polish and pleasing optical characteristics.
