I call the first one a 'Marine Cuff' because of the colors
It's made of opaque matte black Tila beads, dark purple and opaque light blue Swarovski beads, and also size 11 TOHO beads.
For the bracelet in the second picture, I used the same Tila beads, TOHO beads, and round glass fushia beads
Hope you enjoy these designs!
