Fiametta: Lab-Grown Diamond Jewelry by Merill Hollander

Merill Hollander founded Fiametta in New York in 2023 after a career that started at Bloomingdale's buying desk and ran through a Wharton MBA. The label works exclusively in lab-grown diamonds and frames itself as a rewrite of fine jewelry's rulebook, drawing openly on Hollander's experience as a queer woman deciding which traditions to keep and which to drop.

Jewelry

Fiametta's name translates from Italian as little fiery one, and the pieces in this first grid are built to be worn as often as a wedding band, not saved for a single occasion. Hollander's background in merchandising at Bloomingdale's shows up in how wearable the shapes are. The diamonds are lab-grown throughout, which the brand treats as a starting principle rather than a footnote.

Personal fine jewelry in gold

A second grid of the same instinct: pieces meant to be bought for yourself, not gifted on a schedule someone else set. That self-purchase framing is central to how Hollander talks about the brand, and the diamond shapes here keep it consistent rather than chasing novelty for its own sake.

By the third pass through the assortment, the pattern is clear: classic settings, contemporary sourcing, and very little interest in occasion-only jewelry. It is a young house, barely two years old, so what you are seeing is still the first chapter of a specific argument about how fine jewelry gets made and worn.

The case for lab-grown diamonds

Fiametta is betting that lab-grown diamonds and a personal story can do the work that decades of heritage usually do for a jewelry house. Two years in, the pieces are consistent enough that the bet reads as more than marketing. Whether it holds up over a longer run is still an open question, but the point of view is not borrowed from anyone else. For Fiametta's lab-grown diamonds, I would look for a few more pieces to wear alongside them in rings and necklaces for layering.
