This detailed mitochondrion pendant displays the outer membrane, inner membrane, ribosomes, DNA, and more. A beautiful and unique piece of jewelry, it is also delightful to hold and touch while concentrating on one's biochem homework or dissertation. Hand cast from pewter and then antiqued and polished, it comes on an 18 inch or 32 inch gunmetal chain.
