We personally select only quality supplies for the JA Beaded Collection.  
This Black Hematite stretch bracelet is constructed with 1mm magic stretch cord which is the strongest available = protects against stretching too large and breakage. 

*Shown below with an additional hematite heart bracelet and hematite and silver TOHO bead bracelet! (check the preset stack collection for this combination)

**Be aware that rolling stretch bracelets over the hand is the proper way to minimize stretching and breakage**
JA leverages an epoxy glue to cover all knots for added reinforcement.
