7.21 Ct. Cabochon White Opal from Australia

I am pleased to introduce a truly charming example of natural Australian opal, offered by The Natural Gemstone Company, one piece that will appeal to collectors and designers alike. This is a White Opal, a multi color, opaque oval that weighs 7.21 carat, with dimensions 19.53 x 10.94 x 6.13 mm. The gem has been expertly shaped into a cabochon cut that showcases its internal color play across a smooth domed surface, and it displays medium color intensity with flashes of pink, green and soft blue that move as the light and angle change. The overall polish is excellent, giving the stone a clean reflective finish that enhances the subtle opalescence typical of quality white opal. This opal is natural and untreated, which means there has been no enhancement, and its origin is Australia, a region renowned for producing beautiful, stable white opal material.

As a salesperson with a deep practical knowledge of gemstones, I want to highlight what makes this White Opal desirable in everyday wear and in bespoke jewelry projects. The cabochon profile is ideal for white opal because it maximizes the way light is captured and diffused through the silica layers that produce the play of color, creating patches and flashes that seem to float beneath the surface. Because this piece is opaque with multi color flashes, it offers consistent visual interest even in softer lighting, while the medium intensity of color ensures that the hues are lively without overpowering a setting. The oval shape and balanced proportions make it versatile for use in rings, pendants or statement earrings, and the generous measurements give jewelers substantial material to work with for a focal mounting. The excellent polish not only enhances beauty, it also indicates careful lapidary work that will sit comfortably against a skin surface and reflect light attractively.

From a technical and care perspective, this opal benefits from being natural and unenhanced, attributes prized by traditional collectors and contemporary buyers who value authenticity. The 7.21 carat weight and dimensions allow for design flexibility, yet the stone should be treated with the same mindful care as other opal types. Although Australian white opal is generally more stable than some other varieties, it is best to avoid abrupt temperature changes and prolonged exposure to chemicals that can dull the polish. For setting recommendations, a protective bezel is often preferred for cabochon opals as it secures the profile and reduces the chance of knocks to the edges, while a prong setting can be used if the design emphasizes the dome and requires minimal metal coverage. When designing a ring, consider a lower profile bezel or a halo of small accent stones to complement the opal without overwhelming its gentle color play. For a pendant, a simple bezel with a soft matte metal back can provide both protection and a warm contrast to the opal surface.
