There are 24 big, 7mm to 13mm beads, graduated in size, along this strand. They are shiny and sparkly and beautiful, natural Prehnite, with some minor, matural inclusions as one expects to find in Prehnite. They are hand cut in the twist shape, which cannot be easy to do, and the result is the most stunning and special strand of beads waiting to be made in to exceptional jewellery.
