Brilliant Earth marks 20 years with Swiss-made diamond watches

Brilliant Earth stepped into watches with The Solstice Collection, a two-model debut that turns its 20th anniversary into a Swiss-made category crossover. The jewelry brand’s first watch line arrived as a limited release of 100 pieces worldwide: 65 Summer Solstice watches in moss green and 35 Winter Solstice watches in white.

The collection keeps Brilliant Earth’s visual language unmistakably jewelry-first. The Summer Solstice pairs its green dial with a restrained, polished case, while the Winter Solstice uses a snow-white dial, four baguette lab-diamond markers, and a green calfskin leather strap. Brilliant Earth says the Winter Solstice’s markers total 1/15 carat weight and that the model also includes an exhibition caseback and a polished stainless steel case, details that push the watch closer to a collector’s object than a standard fashion crossover.

Price places the launch firmly in the accessible-luxury lane for a diamond-adorned Swiss watch. The Summer Solstice is priced at $3,995, while the Winter Solstice is $4,995. Brilliant Earth says both watches are available on its website and in select showrooms, a distribution strategy that keeps the rollout tight rather than mass-market.

The manufacturing partner matters here. Each Solstice timepiece is made in Switzerland with Louis Erard, the independent Swiss watchmaker Brilliant Earth says carries nearly 100 years of horological heritage. That collaboration gives the launch a sturdier watchmaking pedigree than many jewelry brands that simply borrow horology’s visual codes without leaning into the craft behind them.

Brilliant Earth was founded in 2005 by Beth Gerstein and Eric Grossberg with a mission to make the jewelry industry more transparent, sustainable, inclusive, and impactful. The company says it now operates 42 showrooms across the United States and serves customers in more than 50 countries, a scale that helps explain why a watch launch can function as more than a side project. It is also part of a wider anniversary push that includes a 20th Anniversary Collection page and a Mission Report released on March 5, 2026, marking two decades in business. In a market crowded with conventional luxury watch launches, Brilliant Earth is trying to make time itself feel like an extension of its signature stones and symbols.
