4.85 Ct. Cabochon White Opal from Australia

This specimen is a White Opal, a 4.85 carat oval cabochon with dimensions 13.79 x 10.23 x 7.36 mm, sourced from Australia and presented by The Natural Gemstone Company. The opal is opaque with a multi color play of color, evaluated at medium color intensity and finished with an excellent polish. The cabochon cut and the gently domed oval profile maximize the stone's internal diffraction, allowing flashes of green, red, and blue to emerge as the viewing angle changes. No enhancement has been applied to this natural opal, and its structural integrity and surface finish have been preserved through careful cutting and polishing. The size and shape make the gem a versatile candidate for a range of settings, while the medium intensity of its color ensures a balanced presentation that will integrate well with both simple and more elaborate designs.

In a jewelry setting this opal’s vibrant multi color display will stand out through contrast and movement, providing a focal point that reads clearly against metals and accent stones. Set in a bezel the cabochon will present a smooth silhouette that emphasizes the play of color under everyday light, while a well-proportioned prong setting can allow additional light to interact with the stone, enhancing dynamic flashes. The oval outline suits ring, pendant, and bracelet applications, offering balanced proportions for finger wear and central prominence for pendants. Given its natural, untreated origin and excellent polish, the opal benefits from protective mounting and routine care, avoiding prolonged exposure to harsh chemicals and strong impacts. The Natural Gemstone Company provides this description to assist designers and buyers in assessing how the gem will perform in finished work, noting the combination of Australian origin, cabochon cut, and multi color character as distinguishing attributes that contribute to its visual impact in any jewelry setting.
