0.74 Ct. Multi Color Cabochon Black Opal (Dark Opal) from Australia

This striking Black Opal Dark Opal from The Natural Gemstone Company offers a rare combination of size, shape, and natural color intensity that makes it particularly well suited for custom jewelry, especially when compared to the many treated or assembled opals on the market. At 0.74 carat and measuring 7.50 x 6.33 x 2.73 mm, its oval cabochon profile gives designers a reliable and versatile platform for bezel or prong settings, allowing the intense play of color to dominate the design without competing with complicated mounting details. The gem is opaque with a vivid multi color display, showing deep blues and vibrant greens that sit on a dark base, and it benefits from very slightly included clarity when evaluated at eye level, an excellent polish, and absolutely no enhancement. Sourced from Australia, this stone compares favorably to many similar sized opals that are often heat treated, dye enhanced, or assembled as doublets and triplets, because this piece is a single, natural, untreated cabochon with a depth of color and surface finish that maximizes visual impact.

For jewelers and customers seeking a superior foundation for custom work, this Black Opal Dark Opal stands apart in value and uniqueness. The oval cabochon shape is easier to set and secure than irregular freeform cuts, yet it retains more character and individuality than mass produced round stones. Its modest carat weight and compact dimensions are ideal for creating elegant rings, pendants, or a statement pair of earrings where the emphasis is on color and contrast rather than sheer size. Compared to more common light opals that rely on brightness rather than color contrast, this dark opal offers a dramatic backdrop that enhances metal choices such as yellow gold for warmth, white gold for contemporary contrast, or platinum for a sleek, museum quality effect. Because the stone is untreated, it delivers long term stability and authenticity, and because it is cabochon cut and well polished, it presents a smooth, durable domed surface that performs beautifully in daily wear when set correctly. If you are considering a custom piece, The Natural Gemstone Company is ready to assist with design suggestions that take full advantage of this opal, ensuring your finished jewelry will be both distinctive and enduring.
