I seem to be on a roll with these anonymous blue stone beads!  This time, I’m using them as the main bead in a necklace, which is accented with some great shell beads that show the shell’s spiral in the centre.  I’m not sure which type of shell they came from, but the way they’re cut is absolutely fantastic.  I was completely taken with them when I bought them, but this is the first time I’ve actually used them.
