Bring needle and thread through the next cube bead. Repeat using the 6mm potato pearls (string on 25 pearls), and then with the 4mm pearls (string on 45 pearls).
Weave the thread into the diamond, knot firmly, add glue if desired, weave into the diamond some more, and then trim close to the beadwork.
Repeat with the other side of the clasp.
