Looking around on the bnf I stumbled across this press photo from 1932 with the following description:


" Un collier de 15 millions de dollars provenant des joyaux de la couronne de Russie et que vient de laisser en mourant Mme Edith Rockefeller, Mc Cordmik de Chicago "

A necklace worth 15 million dollars with a provenance of the Russian crown jewels that was left? by Madame Edith Rockerfeller.

The stones look like emeralds to me but I don't think I've seen this piece before.
