Essex glass" has nothing to do with the county of Essex! The technique was brought to England from continental Europe by Thomas Cook in the 1860s. At the same time, a well-known miniature painter and darling of the Queen Victoria named William Essex. It didn't take long for people to think that these delicate paintings were the work of the artist, and... the name stuck! All our vintage rings.

Authentication & Certification

Charlotte Rey and Anne Borde help individuals who ask themselves a thousand questions when selling their jewelry(s). How much is it worth on the market? Is it solid gold or gold plated? How to identify stones? And, after all, what if it came from a prestigious house?

With the jewel in hand, the founders of Castafiore determine the nature of the materials, the weight of the gold, the carats of the stones, etc. They are also looking for the trace of a hallmark, a sign of a possible renowned jeweler.

This expertise then gives rise to a digital certificate of authenticity registered in the Blockchain (GoodsID), in other words traceable and unfalsifiable; it will accompany the jewel throughout its existence, over the course of its owners.



Anne Borde worked for 30 years in the world of auctioneers and auctions, notably in Drouot. She has inventoried countless collections and estates; she had thousands of objects in her hands which she examined from every angle. His sharp eye misses no nugget.
