TRUSTED DEALERS, AUTHENTICATED JEWELS

JWL WORKS EXCLUSIVELY WITH EXPERTS IN VINTAGE FINE JEWELLERY

Our TRUSTED DEALERS Are The Go-To Suppliers For Pro Collectors All Over The World

They trade with private buyers, as well as with other dealers, from their boutiques or private showrooms, at international fairs or behind booths in key jewellery districts.

Our TRUSTED DEALERS can be found building -or helping build- magnificent collections in London's Mayfair, in trade shows from Hong Kong to Las Vegas, at the end of Zurich's Bahnhofstrasse or by the Four Seasons, both in Geneva and Milan.

Their REPUTATION is international, industry-wide and hard-earned. Some of our Trusted Dealers have spent 30 years and others over a century finding, repairing and selling the world's finest jewels.

What AUTHENTICATION Means

Authentication is the expert process of verifying what a piece is and what it is not. To do this, EXPERTS and certified bodies inspect from materials and period clues to construction and maker signatures.

For signed pieces, Dealers focus on SIGNATURES and maker’s marks from Houses and ateliers, as on serial or unique production numbers.

For unsigned items -a gold bracelet with no house signature, for example-, the authentication focus is on material VERIFICATION and craftsmanship checks: confirming precious metals and stones, construction and quality, cements value.

In most regions, jewels cannot be sold if they are not hallmarked. This is to indicate that an independent body has tested the metal and guarantees fineness.

A Word on Reports & CERTIFICATES

When pieces include precious stones, dealers typically rely on independent gemological REPORTS.

For diamonds, labs such as GIA (Gemological Institute of America) issue reports evaluating quality and value based on carat, colour, clarity and cut.

For coloured GEMSTONES and pearls, specialist labs -such as Gübelin and SSEF- report identity, treatments, and geographic origin.
