Superb and extremely rare ruby and diamond ring
Set with a cushion-shaped ruby weighing 25.59 carats, between shield-shaped diamonds weighing 2.47 and 2.70 carats, signed Cartier, numbered, French assay and maker’s marks, size 54, case signed Cartier.
The described ruby exhibits a very impressive size and weight of 25.596 ct, combined with a highly attractive colour and a fine purity. Its colour is further pronounced by its well-proportioned cutting style, resulting in vivid red hues due to multiple internal reflections. Due to complex geological formation processes rubies of such quality generally are found in small crystals and only very exceptionally in such a size as the present stone.
