Set of 12 Rock Sharpe fine intaglio cut crystal tall champagne coupe glasses. These beautiful stems are the Kyber pattern, engraved on stem shape #1010. The original company was called Cataract Glass out of Buffalo, run by Alfred Sharpe.
Libbey renamed it the Sharpe Division, and it's likely these were made during that time. Each measures 6 3/4 h. Excellent condition with no chips, cracks or damage.
