Herkimer Diamond Specimens
Herkimer Diamonds are cut from clean quartz crystal that has
been hand-graded for clarity before faceting.
Herkimer Diamonds look like real diamonds and, like real
diamonds, can scratch glass
These diamonds are mostly set in sterling silver pendants
but top Herkimer diamonds do make exquisite ring stones
