Terahertz Sterling Silver 4mm Faceted Beaded Necklace 18"

This is a synthetic stone named terahertz stone, that is synthetic and claims to have metaphysical properties. While I can't make any claims to this, the internet is full of information. What I know is that it's a man-made silica gem that has a beautiful luster of a slight bluish-black. The facet junctions are nice and sharp on these 4mm faceted beads. They pass the "ice test" where they will literally melt into ice.

The beads are each wrapped by me in solid sterling silver with a weight of 5.5g and 18" in length.
