These are the semi-precious Prehnite smooth and faceted beads we currently have in stock.
Prehnite is a fairly rare material in the bead market, but we are starting to see a few choices become available. The color is a light green with a bit of a yellow tone - in fact, this stone is sometimes confused with jade. Many of the beads will have flecks or needles of black inclusions which are characteristic of this gemstone. This gemstone is also sometime mis-spelled "phrenite".
These Prehnite beads are cut into a fully faceted briolette or "pear" shape. Note from the picture that they have tiny flecks and needle shaped inclusions of black that are common in this gemstone. Sizing in this group is very uniform so all are being sold in the same size category. Each bead will be between 7-8mm in both height and width. Holes are small, but will accommodate 0.3mm stringing material.
