Our online full text Rare & Antique Book Library

We relaunched our Rare & Antique Book Library as streaming books, making reading them as easy as watching a Youtube video. We will be adding books every week.

Books are best read on laptop or PC. Don’t forget to check the navigation bar of the book viewer: you can read books in “single page mode” or “dual page mode” and if the pages are too small try the “full screen icon”.

To find out a bit more, we posted some basic guides on Art Deco Jewelry and Art Nouveau Jewelry and Victorian Age Cameos as well as a large number of Christie’s and Sotheby’s auction previews for collectors written by several of America’s leading experts in the field.

Museum collections and Virtual exhibitions

A large group of museums shared their images of their collections in jewelry, gems and other gold treasures with us. We show them as a museum collection for each museum.

In addition we collaborated in the past with National Geographic, the Getty, Prince Claus Foundation, MKG Hamburg, Afghan National Museum to showcase their in-museum exhibitions. They can be found in our exhibition archive.
