Magnificent vase by Molly Cohn of Cohn-Stone Studio. Sweeping tortoise shell vase with satin black glass base and spiral. Stands approximately 20 inches high and is approximately 12.5 inches wide. The Tortoise Shell series is a magical marriage of classical forms and boldly elegant color. The result is a contemporary work of functional art with a timeless beauty that fits in a wide variety of environmental styles. Based on a process developed by artist Michael Cohn in the early 1970's, the Tortoise Shell pattern has evolved over many years into one of the Studio’s signature lines. Each piece is created with a unique richness and depth of patterning—a timeless combination of contemporary and classical art.
