Introducing Queen Stephanie,

A High-End Large Pear Boulder Opal Engagement Ring with a VS2 Diamond Halo

The centerpiece of this engagement ring is a large, elongated pear-shaped boulder opal from Queensland, Australia—measuring just over 23 millimeters long. Its N5 body tone places it in the “dark opal” category, and the color play is distinctly directional: green-blue fire dominates, with flashes of yellow and orange appearing when the ring catches the light from the right angle. It’s the kind of stone that rewards movement, showing different character depending on how it’s worn.

Set in solid 14k yellow gold, the ring has a slim, delicate profile despite its size. A halo of pavé-set diamonds surrounds the opal, with a total of 67 round brilliant stones (approximately 0.67ct combined weight), averaging VS2 clarity and H–J color. A split-shank design keeps the ring balanced visually and prevents it from looking heavy on the finger, even though the top spans approximately 27 millimeters from end to end.

The stone itself is secured in a low, protective setting suitable for everyday wear—something important for an opal engagement ring of this size. The craftsmanship is clean and structurally sound, made by Master Jeweler Juan Yah, a Los Angeles bench jeweler with more than five decades of opal-specific experience. Though his name is not widely known in retail circles, he is the jeweler trusted by many designers and stores throughout Southern California for their opal pieces, repairs, and custom work.

Overall, this ring combines substantial presence with refined proportions: a large, high-quality Queensland boulder opal, a bright VS2 diamond halo, and a setting designed to be worn comfortably as an engagement ring.
