Unfortunately, your photo lacks details that would allow certain identification.

ONLY green a-speo star beads are "watermelon" beads (in my opinion).

The name is nonsensical for similar beads of other colors (such as blue and red), and meaningless for any other cane types. To just call them "melon" beads would be even worse.

But I can imagine that your beads are late a-speo beads (based on outlines and the indications of stripes).

Be well. Jamey
