2.73 Ct. Multi Color Boulder Opal (Ironstone Opal) from Australia

This listing describes a single, natural boulder opal, ironstone opal, cushion shaped tablet cut gemstone weighing 2.73 carats. The piece measures 8.67 x 7.98 x 3.55 mm, and presents an opaque body with multi color play across the surface. The cutting style is tablet, carefully executed to retain the natural ironstone matrix while presenting broad areas of precious opal color. Color intensity is assessed as intense, with vivid greens and flashes of blue and orange visible across the face depending on orientation and lighting. Clarity is graded very slightly included when evaluated at eye level, with inclusions integrated into the ironstone matrix and not detracting from the overall visual impact. The surface has an excellent polish, providing a smooth, reflective finish that enhances color play and elevates the stone for use in custom jewellery settings.

This boulder opal originates from Australia, and is presented without any added enhancement, retaining its natural state. The tablet cut and cushion outline make this specimen well suited to bezel mounting or low profile settings where the ironstone backing can be showcased alongside the opal color. At 2.73 carats and with the listed dimensions, the gem offers a balance of presence and practicality for ring or pendant applications. All information is provided by The Natural Gemstone Company, and reflects an emphasis on accurate measurement, grade description, and provenance.
