90.00

Although not terribly rare, germanium is ten times more expensive than silver due to the expense of getting it to 99.999% purity, as in this sample (which happens to be the most commercially available grade). A beautiful crystal with a faint yellow-green tinge and multi-colored surface, weighing about 10 grams and embedded in a 2x2 inch (50x50mm) block of crystal clear Lucite acrylic
