I am not sure I ever posted a list of jewels "sold by princess Lilian". But it is public knowledge that some jewels were sold at Christie's Geneva, in 1988 or 89, by princess Lilian.
I wrote an article about it in Point de Vue, a long long time ago. Actually it may have been one of my first article about jewelry, a long time before internet, and many of you, were even born.
Some of the jewels in this sale ( I remember there might have been about 20 or 15 pieces in the sale ) were bought back by the jewelers who had made them. Cartier bought the queen Elisabeth diamond tiara, and Van Cleef & Arpels, bought a sapphire and diamond brooch set in "serti mystérieux".
The other pieces were mainly Cartier and van Cleef & Arpels jewels. But I am 100% sure there was no piece of antique jewelry in that auction and that the famous emerald cabochon brooch was not in it.
