I am perhaps best known for my collection of diamonds from Pike Co. Arkansas, USA. These crystals range from 1.43 carats to 8.82 carats. It has taken years to track down these historic diamonds, which are some of the largest and finest ever found at the Crater of Diamonds State Park. They were on display as part of the 2008 American Minerals Treasures exhibit (and book) at Tucson. Range from 8 mm to 14 mm. (Author: Jim)
