Mammoth ivory ranges from 10,000 to 40,000 years old and has been preserved in the permafrost in Alaska and Siberia. It has an outer layer commonly called bark ivory which is harder than the inner ivory or dentine. Frequently, the inner dentine will be completely rotted away while the bark is still usable. The quality of Mammoth ivory varies considerably from rotted to very solid tusks which can be sawed into dimensional materials. With rotted material referred to as D-grade and saw-able solid material as A-grade, Mammoth ivory is approximately 15% D-grade, 15% C-grade, 60% B-grade and 10% A-grade. The material we use to make Jessica Kagan Cushman bangles is all A-grade.

Each bracelet is hand carved and designed by Jessica Kagan Cushman Studio.
