Despite their diamond misnomer, Herkimers are are actually six-sided, double-terminated quartz crystals and are relatively valueless. Nevertheless, unscrupulous jewelers during the Civil War often tried to pass them off as the more precious variety.  In our take on classic diamond solitaire studs, a hand-hewn sterling silver bezels grip the Herkimers with square prongs.  Every unique stone is chosen and set by hand; expect yours to have irregularities like cracks, dark spots, and milky-colored mineral impurities.  Stones measure about 3/8" at their widest point.  Posts and earring backs are sterling silver.
