An interesting feature of this auction is the appearance of a lot with enormous historic significance bearing Lot No 279 titled “Historically Important Sapphire and Diamond Brooch and a Pair of Ear Clips, Circa 1900,” with an estimate of CHF 280,000 – 480,000 (USD 305,656 – 523,982). This historic set of jewels was part of the Royal Jewels belonging to the Romanov Family, smuggled out of Russia during the 1917 revolution.

The jewels belonged to Grand Duchess Maria Pavlovna, the aunt of Czar Nicholas II, the last Czar of Russia, who was ousted during the 1917 October Revolution. The Grand Duchess entrusted the jewels to her friend, the British antiques dealer and aristocrat, Albert Henry Stopford to smuggle them out of Russia into Great Britain. Stopford, dressed in ordinary workman’s clothes, collected the jewels from the Grand Duchess’ home, dismantled them, wrapped them in old newspapers and carried them together with 241 other pieces of Pavlovna’s jewelry, on a ten-day journey across the North Sea to the safe custody of a British Bank. The Grand Duchess never made it to London to collect the jewels and died in Paris, France, on her way to Britain through a circuitous route through the Caucasus and several European countries. Pavlovna’s jewelry eventually became the possession of her daughter, Princess Elena of Greece and Denmark.
