Fifty years on Forty-Seventh: a dealer opens the books

§1A handshake was the ledger.

While the industry spends its summer arguing over who will own De Beers, one of its longest-serving dealers has published an account of what owning a diamond business actually felt like. Jeff Pancis, founder of the natural-color specialist Pancis Gems, entered New York's 47th Street Diamond District in 1976; his new memoir, 'Unveiling Rarities,' compresses the nearly fifty years since into a dealer's-eye history of the trade, out now in hardcover, paperback and Kindle editions, as reported by INSTORE.

§2The wound every dealer fears.

The book's spine is the district itself — a few Manhattan blocks where multimillion-dollar transactions moved on a handshake and a man's word was his collateral. Pancis, the son of Holocaust survivors, traces the arc from his 1976 apprenticeship through decades of international negotiations, and through the 1999 robbery he describes as nearly destroying the business — the kind of loss that, in a trade built on consignment and trust, wounds reputation and inventory at once.

§3Memory, just before the database.

The timing gives the memoir an unintended sharpness. The handshake economy Pancis documents is precisely what the industry's current convulsions — certificate scandals in Vietnam, algorithmic pawn valuations, marketplaces that X-ray every watch and stone — are engineered to replace. What was once vouched for by a family name on 47th Street is increasingly vouched for by a database. The gain in security is real; Pancis' book is, among other things, an accounting of what the district had before it needed the database.
