A fine, old Russian aquamarine crystal from the Adun-Cholon Range of Russia. This classic, sharp and very gemmy crystal is notable for the symmetry of form, sharp termination and also the intense steel-blue color. The gem mines here started in 1723. This crystal probably dates to the Czarist Era, but no proof. Ex. Roland Sherman Collection. Weighs 11.74 carats.
