Vintage Tanzanite & Diamond Platinum Ring

Estate platinum ring featuring an emerald-cut tanzanite framed by diamond-set, marquise-shaped shoulders for a refined vintage look with strong showcase appeal. The saturated blue center and bright diamond accents create an immediately recognizable “hero-stone” silhouette that merchandises well in estate cases, gemstone bridal alternatives, and elevated gift stories—an easy add for clients seeking color-forward sophistication in a classic, wearable profile.

The Story

Made by hand, when the continental ateliers still set everything by hand.

The kind of piece a serious retailer builds a vitrine around.

The provenance for this piece is recorded against its piece-level documentation file. Approved partners can view full hallmark identification, period-appropriate setting techniques, condition history, and prior-ownership notes alongside the piece.

For the showroom conversation, the short version is the one the case card carries: era, atelier or designer, and what makes the piece worth a vitrine. The long version is for the client who's asking the right questions.
