The deeper story

Stone Story

Almost all commercial black onyx is treated chalcedony. Gray or brownish stone is processed with sugar and sulfuric acid, which carbonizes organic material inside the porous structure to produce that even, stable black. The process has been documented since ancient Rome, making it one of the oldest beauty treatments still in active use.

Made With Purpose

How the piece will be worn determines whether the toggle is the right closure. The mechanism relies on the T-bar's width and gravity rather than a spring-loaded lock, reliable for necklaces in relaxed positions and less so for active wear or high-value pieces where closure reliability is a priority.

Product & Assortment

A piece of estate jewelry already has a story. Ross-Simons has long carried estate pieces alongside new collections, and what that gives customers is access to jewelry with history, character, and a perspective that new production simply can't replicate.
