These already-rare bright green Jeffrey Mine grossulars have virtually DISAPPEARED since the closing of the mine. Now and then, you will find a little specimen with tiny crystals, but not sizeable crystals such as this (to .45 mm), with the TOP glowing green color and gemminess! As hard as it is to find one of these now, it will only get harder. Although small as a specimen, this is of truly superior quality! 2.5 x 2.4 x 1.3 cm
