1.20 Ct. Multi Color Cabochon Boulder Opal (Ironstone Opal) from Australia

A whisper of ocean and sunrise rests within this oval 1.20 carat boulder opal, a dreamlike jewel that seems to breathe color with every tilt. The cabochon surface holds a soft, luminous dome where green, blue, and flashes of gold ripple like light across water, each hue moving with intense color intensity and an excellent polish that invites touch. This is Boulder Opal, Ironstone Opal from Australia, an opaque beauty with a soulful presence that reads like a promise. Mounted in an engagement ring, a pendant, or a keepsake brooch, this stone becomes a private horizon, a tiny landscape that captures memory and meaning, rendered in a shape that is both classic and endlessly flattering.

For custom work this opal is a jeweler and wearer delight, the oval outline and modest dimensions of 7.34 x 6.22 x 3.97 mm offering perfect balance between presence and practicality. At 1.20 carat the stone is substantial enough to command attention, yet intimate enough to sit comfortably against skin, making it ideal for rings destined to be worn every day or for sentimental pieces meant to stay close to the heart. The cabochon cut gives the stone a gentle dome that softens light, shows off the opal play, and lends itself to a variety of settings, from elegant bezels that cradle its ironstone base, to delicate prongs that let light travel beneath the surface. There is no enhancement, the color is wholly natural, and the ironstone backing adds stability and warmth, making this boulder opal a practical choice for bespoke designs. At The Natural Gemstone Company we appreciate how form and spirit meet in pieces like this, we can advise on settings that honor the stone, and we welcome the chance to help you create an engagement ring or heirloom that will carry this Australian treasure into a lifetime of moments.
