Delicately pierced cathedral shoulders evoke a late-Art Deco aesthetic, framing the oval opal with fine single-cut diamonds. The opal’s soft, translucent body color flashes greens, oranges and violets under direct light, creating an understated yet vibrant focal point. A well-finished platinum gallery and tight prongs provide secure, everyday wear, while the included Japanese gem certificate supports authenticity for resale or insurance.
