Unknown GIA-Certified Unheated 2.25ct Peach Sapphire In White Gold Diamond Halo Ring

Without heat treatment, the stone’s natural imperfections — including an amazing spray of tiny bubbles — are there for the viewing, but with the help of a very nice faceting job this sapphire’s natural brilliance manages to coexist with all of its internal chaos.

The GIA report confirms the following details:

Dimensions: 7.59mm x 6.76mm x 4.81mm
Weight: 2.25 carats
Cut: Modified brilliant on top and step cut on the bottom
Treatments: None detected

We chose and set the stone in May of 2023, but the ring itself is a preset mounting from jewelry giant Stuller, probably around 15 years old. It’s a straightforward double halo design intended as an engagement ring with a 1.75 carat diamond. We acquired it from a customer who wanted her diamond reset in a new ring.

We like putting unusual stones in our pre-owned engagement rings, the more traditional the better. It’s our way of saying, « Okay, ring, you’re officially relieved of Diamond Engagement Ring duty. Your new assignment is ALL ABOUT THE DAIQUIRIS!! »

The tiny diamonds set on the halo and the split shoulders range in size from around 1.2mm to 1.5mm. Stuller generally uses stones in the G to H color range and either SI or I clarity. We think these are H color and low SI clarity with a total weight, for all 70 stones, of between 0.55 to 0.65 carats.

We’re not sure what Stuller’s current policy is, but this ring predates the customary use of lab diamonds, so we can confirm all diamonds are natural, earth-mined and untreated.

The face of the ring is 11mm wide and 12.6mm tall (0.43″ x 0.50″). The split shank tapers to a single band in the back, 1.8mm wide and 1mm thick. The inside of the band is stamped with the Stuller hallmark and « 14K. »

Currently a size 5-3/4, we will resize at no charge for full-price buyers; otherwise, resizing is negotiable.

This ring weighs 3.8 grams.
