1.20 Ct. Blue Cabochon Boulder Opal (Ironstone Opal) from Australia

A single dream of ocean dusk and midnight bloom, this blue boulder opal, ironstone opal, carries the hush of Australian fields and the quiet fire of buried light. At 1.20 carat, oval in shape and warmly opaque, it sits as a small moon of color with dimensions measuring 8.73 by 5.39 by 3.26 millimeters, a cabochon cut that smooths its surface into a luminous dome. The vivid color intensity seems to move beneath the polish, veins of cobalt and ultramarine that shift as if tide and sky are being stirred beneath glass. Unenhanced and true to its origin in Australia, this gem shows an excellent polish that catches and softens light into a gentle, breathing glow. Hold it and you feel the weight of promise, an intimate piece that invites a closer look, a private map of color that will sit close to the skin and close to the heart.

For custom jewelry this opal is a perfect companion, especially for engagement rings and sentimental pieces where shape and size matter as much as color. The oval cabochon profile lends itself to elegant bezels and low prong settings that protect the stone while showcasing its full face, ideal for daily wear and quiet gestures. Its compact dimensions make it versatile for stacking, for side stone pairings, or for a solitary, central mount that reads like a secret kept between two people. Jewelers will find the balance of depth and surface ideal for settings that cradle rather than crown, making the design feel personal and enduring. Offered by The Natural Gemstone Company, this Boulder Opal, Ironstone Opal, invites a custom design that remembers light and memory in equal measure, a stone that promises to age into a story, to collect every glance and every vow it witnesses.
