Surely one of the very first adornments, beads made out of seed and plant connect you back to nature.
palomar.edu tells us that:
"With the exception of amber and coconut pearls, most botanical jewelry is made from relatively inexpensive materials. Polished wooden beads, colorful seeds and pieces of palm, bamboo and tropical hardwoods are strung on fine nylon filament or gold and silver chains, producing attractive necklaces and bracelets that rival any synthetic costume jewelry. In terms of aesthetic beauty and intrinsic value, plant jewelry may rank as high as any gemstone. Exotic seed necklaces from native cultures throughout the world often come with fabulous tales about their origins and legendary uses."
