BCR413 Prehnite

BCR413 Prehnite


  • Here’s a new item, a gorgeous piece of Prehnite.
  • A great rock for cutting and any lapidary project.
  • This is a select piece of Prehnite that Shawn has picked out. He says he sees something special in these. Whether it be that it needs thumbed, ground on and tumbled, cut and tumbled or cut and polished , he sees something. Whether you will see what he sees, or whether you can bring to fruition what he sees would be up to you. Of course, with all rocks, there are still risks. There could be fracture lines in the wrong place, the color may change or…Shawn could just be wrong. Regardless, these are much higher quality than our regular tumble material.
  • It measures 6 3/8″ x 4 5/8″ x 5 7/8″ and weighs nearly 6 3/4 pounds.
