This strand is made out of a translucent deep green Pounamu. The beads look quite black inside under artificial light and a lot greener in sunlight. As you can see when back lit they have a wonderful glow. The little slider beads that go into the silver clasp are made out of a light green Pounamu.
The photos below show the colour change in different lighting.
The length is 52cm of beads or 54.5cm in total with the silver clasp (handmade).
I attach the clasp after the strand is sold so the owner can have a say in how long they want them to hang. I do this by adding or removing beads. You can see what a finished clasp will look like on the strand of bright green Cassiar beads.
