The Tereschenko is a spectacular blue 42 carat antique pear brilliant cut.
The original owners of the gem were the Tereschenko family. They were sugar-kings in pre-communist Russia. One member, Mikhail (1886-1956), who held advanced political views, became Kerensky’s Minister of Foreign Affairs in 1917.
It is not known where it was found: theoretically, it may have come from either the Kollur alluvial depo sits in India or from the Premier Mine in South Africa.
By 1913 the Premier Mine had been in existence for barely ten years and since there is no report of it having yielded such a rare and unusual gem, it must be assumed that the diamond is of Indian origin.
