There are a number of collections of large diamonds on display in the treasury, however due to security concerns, the largest of the diamonds in the collection are not pictured here. The largest diamond shown here is 135 cts., while the largest loose diamond in this particular collection is 152 cts. Three other diamonds shown here are 120 cts. each.
