[citation needed] At her death in February 2020, she bequeathed the Fabergé family archive to the Moscow Kremlin Museums.

Back in January 2007, Galerie du Rhône (a Swiss gallery in Sion, 100 miles east of Geneva) asked me if I would like to buy a Fabergé egg they had failed to sell at auction a few weeks earlier.

It contained a tiny vase of flowers and had supposedly been bought from a Russian aristocrat in Basel around 1930, and housed in a French private collection since 1990.

[...] Tatiana Fabergé, who is often quoted in Christie's catalogues, has also placed her signature to a letter supporting the authenticity of this nefarious object.Some years later I came across an almost identical egg to the one from Sion – same design, same height, virtually the same weight, but with different coloured flowers – in something called the Wiazemsky Collection.

Amazingly, this never-before-heard-of treasure-trove was "privately for sale" – brokered, apparently, by the Fondation Igor Carl Fabergé in Geneva, who produced a 76-page document presenting the collection in meticulous detail.
