Seeds, with their seemingly magical properties, seem equal to jewels to me. Here are some of my seed necklaces. These are all from either Belize, Honduras, or Costa Rica. The one made of green peas with the two metal leaves is from either Costa Rica or Honduras and has little pieces of what looks like quartz before and after each green pea. The three on the right are from Belize and are made of both black beans and ceramic beads. The black one on the left with the flat seeds is made completely of seeds, and I really don't know where this one came from or how it came to me.
I'm sure that if I cut one of these necklaces apart and soaked, then planted the seeds they would germinate.
