Victoria Melita:
From ursula's site:
Her second husband presented her some outstanding jewels, but this magnificent sapphire and diamond parure with elements of the "Thistle of Scotland" , the "Rose of England" and the "Irish Shamrock", as diamond stylised three leaf trefoils, was a heirloom of her mother Grand Duchess Maria Alexandrovna, the Duchess of Saxe-Coburg.
She received this parure (tiara, necklace, large stomacher), with the symbolic ornaments of the United Kingdom, from her father, Tsar Alexander II. on the occasion of her wedding with the son of Queen Victoria, the Duke of Edinburgh...she [VM] sold this necklace with the two part stomacher, with a large triangle diamond as pendant to the clover, after the revolution to Cartier, Paris. Above in the picture, the Grand Duchess wore the necklace and stomacher and a matching unidentified tiara with diamonds and sapphires, the whereabouts of which is unknown.
