I don't know that I would buy one, but this is pretty interesting.
A jewelry maker and former naturalist, Hubert Duprat has made jewelry using the larvae of the caddisfly. The larvae of the caddisfly have evolved to coat themselves with gravel to camouflage themselves (first picture).
Duprat removed their gravel coverings, and placed them in tanks with gold flakes and other precious materials.
Here are a few of the results.

When will someone surround me with gold flakes and precious gems and let me cover myself with them?
