It's not a lunar lander, as other-worldly as it looks. This is a typical T4 enterobacteria phage, carefully crafted from pewter to be an exceptionally detailed, delightfully unusual piece of jewelry. Look closely and you'll see the vertex capsomeres, capsid proteins, whiskers, dsDNA, kneecap domain of long fibers, short tail fibers (spikes/pins), and more. It measures 1 inch high, and comes on a your choice of an 18 inch sterling silver chain or a 28 inch gunmetal chain. The gunmetal chain is adjustable - the clasp can be latched on any link.
