2.73 Ct. Boulder Opal from Australia

This elegant cushion shaped Boulder Opal weighs 2.73 carats, and measures 8.67 x 7.98 x 3.55 mm, presenting a tablet cut that highlights its broad surface and rich play of color. The stone is opaque with intense color intensity, and it has been graded as very slightly included when evaluated at eye level, offering character without distracting inclusions. The polish is excellent, producing a vibrant, reflective surface, and there has been no enhancement applied, the origin is Australia, and this piece displays the natural, ironstone backed beauty that distinguishes Boulder Opal from other opal types.

Visually this opal offers a tapestry of green, blue, and warm amber flashes against a dark matrix, the strong color patches coming alive as the stone moves in light. The tablet cut and cushion outline make it ideal for a centerpiece, and the thickness and polished finish are well suited to secure bezel settings or elegant prong mounts that protect the corners. Because it is a natural Boulder Opal from Australia with no enhancements, it carries both aesthetic appeal and geological authenticity, making it an excellent choice for collectors and designers seeking a durable, distinctive opal that balances organic texture with intense color play.
