Queen Alexandra had another Indian necklace - this one made of pearls and emerald beads, but not rubies - which she presented as a wedding gift to her granddaughter, Princess Mary, when the latter married Viscount Lascelles (later Count of Harewood). This necklace was sold with several of the late Princess Mary's heirlooms in 1966: http://www.royal-magazin.de/england/mary-lascelles-harewood/princess-royal-pearl-collier.htm
