A reader has very kindly alerted us to a Cartier Halo tiara for auction in Dorotheum's 10 June 2020 sale.

According to the catalogue the tiara was made in London circa 1930-1935.

It is number 224 on pages 126 and 127.

Has anyone any knowledge of this tiara?

A warm thanks to the reader who alerted us. Looking at the catalogue has made me feel warmer on a very chilly morning for me.
