Introducing Papakōlea,

A Platinum Australian Boulder Opal Ring Inspired by the Green Hawaiian Sands of Papakōlea Beach

At rest, the opal glows with the calm blue of a distant ocean—cool, deep, and reflective.  But under light, it awakens.  Flashes of vibrant green ripple across the surface like sunlight dancing over the green olivine sands of Papakōlea Beach, alive with movement and color.  Each shift of the hand stirs a new current of pinfire light, echoing the play of tide, sand, and sea.

Cut in an angular freeform, the Australian boulder opal—likely from Winton, Queensland—reveals natural bands flowing through the stone like layers of surf meeting shore.  Along the wider edge, warm potch inclusions resemble grains of sunlit sand beneath shallow water, grounding the opal's brilliance in the earth it came from.  Near the top, faint gypsum inclusions rest beneath the surface—not flaws, but quiet traces of nature's hand, formed over millennia.

The opal weighs 11.67 carats, set in solid platinum and framed by six flush-set diamonds totaling 0.06 carats.  Sleek and modern in silhouette, the ring reflects the precision of contemporary Japanese craftsmanship.  It stands as a kindered piece to Hualālai—a mirror of sea to sky, both shaped by time, light, and the beauty of imperfection.

Approximate default ring size 6.50 US.
