12.85 Ct. Black Opal from Australia

I am pleased to present a remarkable Black Opal from our inventory at The Natural Gemstone Company, a freeform, opaque, multi color opal that weighs 12.85 carats, with dimensions of 15.75 by 19.68 by 5.42 mm. This stone displays a medium intense color intensity, with vivid play of color that shifts across green and blue flashes as the angle changes, and it has an excellent polish that brings out its luminous surface. The freeform shape makes this gem especially versatile for creative jewelry designs, and because the cut is listed as n a, the stone has been left in a natural, organic outline that preserves the most attractive areas of color and pattern. As an Australian opal, this Black Opal carries classic oceanic hues and the deep, saturated tones collectors and designers prize, and its opaque base enhances the contrast of the color patches, creating a strong visual presence when set.

Technically, this specimen is offered as a doublet, an enhancement that layers a thin, polished opal slice over a dark backing to maximize color and stability. Doublets are a common and accepted treatment in the trade, they allow thinner opal sections to be used without losing their intrinsic beauty, and they often provide an economical way to enjoy the dramatic appearance of a Black Opal. Because of the doublet construction, care recommendations differ slightly from those for solid opal, so avoid prolonged exposure to water and chemicals, do not steam or ultrasonic clean, and when setting the stone allow for a secure bezel or protective mount that shields the thin opal layer from hard knocks. The backing in a doublet also helps to emphasize the darker body tone, which in turn intensifies the greens and blues you see on the surface, and the excellent polish on this piece ensures that the play of color is lively under natural and artificial light.

At The Natural Gemstone Company we take pride in presenting gemstones with full photographic references and transparent descriptions, this Black Opal doublet is no exception, and we are happy to provide additional detailed images or video clips on request to help you evaluate the surface pattern, color distribution, and thickness of the opal layer. This gem is ideal for a bespoke pendant, a statement ring with a robust bezel setting, or a designer pair of mixed stone pieces where the freeform silhouette can be celebrated, and because the piece is freeform you have freedom to design around its most dramatic color flash. If you would like advice on mounting options, metal choices that complement the blue and green tones, or a secure shipping and handling plan, please contact The Natural Gemstone Company and one of our gemstone specialists will guide you through the options, we can discuss reserve settings, provide a fitting estimate for custom work, and outline proper care to ensure this Black Opal remains a luminous focal point in your jewelry collection for years to come.
