These are Dark Brecciated Red Jasper beads and they are thick beads, heavy and mixed with silver accent beads inter-spaced along black 2mm leather cord. I love the different color of red, black, brown and white all through the beads. The closure is my own design, it's a Silver Plated Om symbol on one side and a 10mm Dark Brecciated Red Jasper cabochon on the other, that hooks with a Sterling Silver Hook.

It wraps three times around the wrist. 
SPECIAL INSTRUCTIONS for accurate length: When Measuring for WRAP BRACELETS locate your wrist bone, then measure your ARM about 2-3 inches up from that bone (one time around.) That will be your measurement for wrap bracelets.
