About the Item

A powerful and sculptural mid-century Brutalist ring set with a natural sapphire that our in-house gemologist has determined is consistant microscopically with a Montana sapphire. The ring is executed in solid sterling silver and retains its original studio character. The ring centers a round brilliant–cut sapphire measuring approximately 4.9 mm and weighing an estimated 0.40 carats as measured in mounting. The gemstone displays the distinctive steel-blue to blue-gray tonality associated with Montana sapphires and, under magnification, exhibits characteristics consistent with unheated material. The sapphire is secured within a deeply architectural, cratered Brutalist mounting, with hand-worked negative space and an organic, almost geological surface texture—hallmarks of American studio jewelry from the 1960s–1970s. The silver has developed a subtle natural patina that enhances the dimensional relief and sculptural depth of the design. Under magnification, the sapphire reveals striking internal reflective forms, including mirrored heart-like shapes created by natural facet junctions and internal color zoning. These visual effects are consistent with unheated Montana sapphires and contribute to the stone’s unique character and individuality. The interior of the band bears a STERLING mark along with an unidentified maker’s stamp, suggesting an independent artisan or small studio production rather than mass manufacture. A bold, collectible example of Brutalist gemstone jewelry—equally suited to a modern collector or as a statement piece with unmistakable presence.

Imperial Topaz Pearl Gold Ring Certified Untreated, London, 1843 Size 10.5
Located in Northampton, MA
This vivid pink imperial topaz ring -hand-crafted in England over 180 years ago- is one of the rarest and most unapologetically regal rings you will ever encounter. A size 10.5 ring, it was originally created for a man. But could of course be worn by anyone today. In the era this ring was created, men wore pearls. And no man would feel uncomfortable wearing a flashy pink gemstone because there is absolutely no other gemstone that looks like this. Topaz is a common gemstone and is typically white. It is irradiated to achieve its popular blue and pink colors. But naturally pink topaz is not common. It is in fact exceedingly rare, considerably rarer than diamonds. And this particular natural pink topaz gem is vividly saturated. It flashes purple. Having reviewed images of the pink imperial topaz necklace and earrings King Charles presented his wife, Queen Camilla...
