Matrix Herkimer Quartz "diamond" w/ Marcasite & Dolomite (rare combo)

Item Description

An impressive and RARE large matrix Herkimer quartz "diamond" from this well-known Herkimer County locale. A striking, sharp, hexagonal, 6.5 x 5.9 x 5.7 cm, very glassy, transparent to translucent "diamond" is dramatically set on a plate of hard silicified shale. The complete all-around crystal has striking modified prism faces and the interior veils add pizzazz (you can see rainbows with the right light incidence). Matrix specimens of this size and quality are rare in themselves. The bottom of the plate is richly covered with dolomite rhombs. A RARE accessory is the dense field of sparkly marcasite microcrystals on the bottom with more on the top. The quartz is complete all-around and nearly pristine, with only gentle brusing/contacting at the tip and along one edge. Exceptional and RARE large matrix combination quartz from the Dr. Barratt Phillips Collection. Value??? We believe a minimum of $750.
