In a letter dated August 9, 1968 Claude Arpels writes to Herbert Singer:

« The 18.54 cts square faceted emerald which you have just purchased through us, came originally from the collection of an Indian potentate known for his love of fine and unique gems.
I succeeded in purchasing it after many attempts during one of my many visits to India. In my opinion, it is one of the finest emeralds of its size and importance which I have ever seen in my jewelry career; its color, clarity and brilliance are absolutely unique for a stone of this size. »

Letters from Louis Arpels dated August 8, 1968 and from their consultant on this sale, R.V. Sullivan of Vartanian & Sons, Inc., dated July 31, 1968, also attest to the exceptional quality of the stone.
