This is my favorite design. It's a classic crochet "shell", repeated on each side of a central chain. In fact, I liked it so much, I made a necklace to match, for my sister.

The freshwater pearl (FWP) that 'anchors' each shell is drilled sideways. That is, it is drilled across the narrow part of the pearl, rather than across the long part of the pearl.

The garnet (a red gem) bracelet second down shows a bead that is drilled across the length of a non-round bead.

The third bracelet is citrine (a yellow gem) beads. Same bracelet pattern, just a different accent bead.

When I tried this the first time I broke the central row of chains. The 28 gauge silver was just too fragile. So I used 24 gauge silver as the "spine", and did the shells in 28 gauge silver.

The pattern for this would be:

Attach 24 gauge wire to first clasp. Chain 3. Add a bead in the next chain stitch. Continue the repeat (3 regular chains and a beaded chain) until the spine is the desired length. (When I do this you can hear me muttering, "bead - space - anchor - space - bead - space - anchor - space...")  Finish off 24 gauge wire and attach second clasp.

With 28 gauge wire, slip stitch into the first clasp. Skip the first chain, and do five (or six, it's your bracelet!) double crochets in the second chain from the end. Skip a chain, and single crochet behind the bead in the fourth chain. Continue this pattern down one side of the bracelet. Then turn the bracelet upside down, and continue the pattern on the opposite side!

I found that I prefer to loop my second single crochet behind a bead into the first one I made. It makes a tighter knot behind the bead, and makes the circles more pronounced.
