8.60 Ct. Boulder Opal from Australia

This listing presents one beautiful opaque 8.60 carat freeform shape multi color opal, identified as a Boulder Opal from Australia, offered by The Natural Gemstone Company. The gem measures 14.40 x 12.10 x 4.70 mm, displaying a tablet cut that flatters its broad play of color, with vivid color intensity and an excellent polish. This piece is natural and untreated, no enhancement, showcasing the authentic character of Australian boulder opal, where the opal layer sits naturally on its ironstone host. The stone is freeform to preserve the best color and pattern, and the dimensions and tablet style make it especially suitable for a striking pendant or a bold bezel set ring, while the boulder backing gives it greater stability compared with thin crystal opal material.

Visually this opal rewards close viewing with deep electric blues and rich green flashes that shift as the stone moves, interspersed with darker banding that adds contrast and depth, the overall effect is dramatic and wearable art. As a salesperson familiar with gemstones I recommend settings that protect the stone edges and emphasize the tablet face, custom designs with a secure bezel or a low profile prong setting are ideal, and the piece integrates beautifully into bespoke designs for everyday wear or special occasion jewelry. The Natural Gemstone Company stands behind the provenance and natural state of this boulder opal, and we can provide additional high resolution images and setting recommendations to help you finalize your design. If you value durable opal with vivid, saturated color and natural origin, this 8.60 carat Australian boulder opal will make a memorable centerpiece in a one of a kind creation.
