3.91 Ct. Cabochon Black Opal from Australia

This striking Black Opal offered by The Natural Gemstone Company is AGL certified, translucent, and classified as Multicolor by lab color standards. It weighs 3.91 carats, and is fashioned into an elegant oval shape with precise dimensions of 13.28 x 8.91 x 5.25 mm. The gem is a cabochon cut, showing a smooth domed profile that maximizes the play of color, and it has an excellent polish that enhances light return. Clarity is graded as very slightly included evaluated at eye level, and the color intensity is described as intense. There has been no enhancement to this natural Australian opal, and the origin is Australia, with certification provided by AGL to document its authenticity and natural character.

Visually this Black Opal presents a mesmerizing, multicolored mosaic that shifts and dances as the stone is moved, with vivid flashes of electric green and neon blue complemented by softer purple and red tones that appear in different lighting and orientations. The translucent body allows an internal depth that magnifies the color patches, creating a dynamic appearance that is rare at this size and weight. At 3.91 carats this oval is substantial enough to serve as a dramatic center stone for a bespoke ring or a signature pendant, and its cabochon profile will sit comfortably in both modern and vintage inspired mountings. Because it is AGL certified, you will receive the assurance of documented origin and natural condition, which is an important consideration for collectors and investors alike.
