About Erstwhile Jewelry
Erstwhile Jewelry is an antique store in New York, NY. The business specializes in vintage engagement rings, custom vintage-inspired settings made with antique diamonds, and wedding bands. It serves customers seeking rare one-of-a-kind antique originals from the Victorian, Edwardian, Art Deco, and Midcentury eras. The shop operates in the NYC Diamond District and offers online shopping with free shipping and returns.
Founded in 2010, Erstwhile was created by fifth-generation jeweler Jared Klusner and his wife, Alisa Klusner. The brand curates extraordinary pieces, drawing on a family lineage that traces back to Hirsch M. Klusner, who opened a Belle Époque jewelry store in Odessa in 1887. The family moved to New York City in 1937, establishing a presence in Manhattan’s jewelry district. Jared Klusner, born in 1975, developed an expertise in discerning exceptional pieces and sourced signed period jewelry for houses like Van Cleef & Arpels and Cartier. His appreciation for vintage engagement rings grew into the Erstwhile brand.
The studio shop handcrafts jewelry using old mine and old European cut diamonds. The team sources rare antique diamonds, including chunky old mine cushions and glittering old European cuts, to create custom rings. They also offer recreations of vintage engagement rings and wedding bands sourced from their sold archive. Every piece is handcrafted to order in their NYC workshop. The collection includes Victorian rings with century-old narratives and Art Deco pieces that intertwine design with historical movements like the Egyptian Revival.
Erstwhile Jewelry brings a deep heritage of five generations of jewelry craftsmanship to New York, offering unique vintage engagement rings and antique diamond settings in the heart of the city.
The store sits on 5th Avenue, just a short walk from East 49th Street, Channel Gardens, and The Exchange.
