Signature Collections

The Turbo Shell

1940s–Present

The ultimate high-society calling card. I buy early (1940s-50s) examples with the original natural patina on the shells. The minute the shells look bleached or perfectly matched like modern replacements, I walk away. Windsor wore these, and structurally, no one does the gold wire-wrapping around natural shell better.

The Cage Setting

1950s–1970s

His most architecturally inventive form. I actively hunt for these—hand-fabricated 18k gold wire cages holding a massive baroque pearl or carved colored stone. To sit down at a bench and fabricate this by hand today would easily double the wholesale cost. You're buying the labor of a bygone era for free.

Vintage Branch Coral & Turquoise

1940s–1970s

Schepps understood how to elevate massive, organic materials into Fifth Avenue jewelry. I look for the 1960s coral suites; pre-1975 coral is legally uncomplicated to trade, and the lack of modern supply makes these legacy pieces a pure value play. Avoid anything that looks newly stabilized.

What Dealers Look For

1

As a smaller, highly creative American house, marking practices were fluid; embrace the variations.

2

Original paperwork is a nice-to-have but entirely unnecessary for collecting and enjoying vintage Schepps.

3

Focus on the tactile joy of the natural materials and the robust, confident construction quality.
