Ostby & Barton Victorian Sapphire Solitaire Ring in 14k Gold

Crafted by the esteemed firm of Ostby & Barton, this Victorian-era solitaire ring highlights a richly hued sapphire set in warm 14k yellow gold. The ring showcases clean lines and a minimal profile that lets the gemstone shine. The sapphire has been upcycled from an older, unrestorable piece and given a fresh polish. The result is a timeless solitaire with renewed brilliance and historical roots.

What we love about this piece is that the prongs are seamlessly part of the ring. A classic design with historical pedigree—Ostby & Barton (1879–1950, based in Providence, RI) was once one of the largest ring manufacturers in the U.S., and their early work remains highly collectible today.
