This 3 dimensional pyramid (or tetrahedron to use it's proper name) is made using lots of sterling silver wire of varying gauges, which have been woven and wrapped together to create a striking pattern on the sides.
I have used Turquoise and Red Agate as well as silver beads. Each side is 1" and 1 1/4" from top to bottom (including the bail and jump ring). The pyramid stands 2/3" tall. This pendant comes with a 17 3/4" spiga chain and is presented in a gift box.
