I recently got these red and pink heart charms, and was really pleased with their look. They are about 5/8" long and was concerned that they might be too big for a charm bracelet, but you can see it turned out nicely. Of course, it is not subtle, but then I don't do a lot of "subtle".
These grey stars are made from shell, and the oval beads are lampwork glass with stripes in white and grey-ish black. I made a necklace, bracelet, and earrings in this style. The accent beads are seed beads from Red Panda Beads. I really like the color-lined clear beads from Miyuki. I like the way they can echo a main color from the piece without having a too strong appearance.
I used large flat discs of brown shell for these earrings, and added a dangle of red glass and brown metallic crystal on the bottom. I think this is a nice color combination, especially for the fall and winter.
Sea glass is so pretty. It is translucent and matte. In these pieces I've used large round aqua sea glass with iridescent aqua shell sticks. I've used patterns of various shades, sizes, and shapes of smaller glass beads to accompany the larger beads.
