0.73 Ct. Cabochon Black Opal from Australia

This exceptional Black Opal offered by The Natural Gemstone Company is a compact treasure, weighing 0.73 carat, with precise dimensions of 8.84 x 6.44 x 2.27 mm, presented in a classic oval shape. The gem is opaque, with a cabochon cut that has been carefully shaped to maximize the play of color and depth, and it displays vivid color intensity under varied lighting. The surface finish is an excellent polish, smooth to the touch and reflective in a way that enhances the internal fire. Originating from Australia, this black opal has not been subjected to enhancement, it is natural and untreated, and it therefore represents the authentic character and rarity collectors seek. The compact size makes this gem ideal for refined bespoke jewelry, and the oval profile is especially versatile, suitable for rings, pendants, or earrings that require a focal stone of distinctive personality.

Visually, this black opal captures attention with a lively mosaic of colors, presenting green flashes that travel across the surface, blue fields that add depth and contrast, and subtle secondary hues that reveal themselves as the stone moves. The cabochon dome amplifies these color flashes, making the patterns appear to float just beneath the surface, while darker body tones typical of high quality black opal lend a dramatic backdrop that intensifies the play of color. In hand, the patterning seems to form irregular patches and pinfire accents, creating an energetic and organic feel, rather than a uniform or predictable appearance. For jewelry design, this stone pairs beautifully with yellow gold to warm the greens, with white gold or platinum to emphasize the cool blues, and with rose gold to bring out any reddish or purple undertones. The stone will perform beautifully under natural daylight and under softer indoor lighting, each condition revealing distinct aspects of its color performance and overall charm.

When considering this opal for purchase, it is important to recognize the combination of attributes that contribute to its value. The carat weight of 0.73 carat in a well cut cabochon, the vivid color intensity, the excellent polish, the absence of enhancement, and the Australian origin together make this a genuinely collectible gem. At The Natural Gemstone Company we pride ourselves on transparent descriptions and accurate imaging, and we encourage buyers to request detailed photos or a video under different lighting if they wish to evaluate the play of color closely. Opal care is straightforward, but it requires attention, avoid exposure to drastic temperature changes, prolonged dryness, or abrasive chemicals, and when setting the stone allow for protective design elements that minimize risk of impact. For daily wear, consider protective bezel settings or secure prongs combined with a slightly raised profile to reduce direct knocks. We can advise on setting options that protect the cabochon and enhance its visual impact.
