01 — Restorative alchemy

We don't repair jewelry. We return a life's worth of meaning to wearable condition.

Inspired by New York's Ostasz Studio, our Sarasota atelier approaches every heirloom as an engineering problem with an emotional answer. Each piece is measured, documented, and structurally reconsidered before a single flame is lit.

Master jewelers with high-end engineering backgrounds handle ring resizing, prong retipping, antique reconstruction, and precision setting — so a grandmother's ring can be worn daily again, comfortably and without worry.

04 — Client stories

Pieces returned, lives restored.

“It takes a lot to impress me when it comes to fine jewelry, and Ostasz Studio in Sarasota, Florida absolutely did. This is not your typical repair shop. The level of craftsmanship, precision, and attention to structural integrity is exceptional. Whether it’s a complicated restoration, stone setting, resizing, or custom work, every piece is treated with the care and respect it deserves. Coming from a jewelry background myself, I especially appreciate the New York influence and the fact that there are no shortcuts. The goal is not simply to make a piece look good again, but to restore it properly so it lasts. Sarasota is extremely fortunate to have this level of talent locally. Ostasz Studio is a place I would personally trust with an important heirloom, and that is the highest compliment I can give.”
Am G / Custom ring
“I highly recommend this place for their craftsmanship and wonderful service! I have small ring size and they were able to customize to fit me perfectly. Ring is gorgeous and sparkly, it keeps getting me tons of compliments (˶˃ ᵕ ˂˶) I have never been this happy to purchase a custom piece before, big thanks!!”
