상품설명
Rhenium is our first precious metal entry to the 10mm cube family; ahead of silver which seems like a more logical choice (that one's still coming) Density cube collectors will suffer in the pocket, as we will, when shelling out to complete this group but at least it's understandable given that they are, after all, precious metals. According to the CRC Handbook of Chemistry and Physics, arguably the most authoritative reference on these subjects, rhenium is the rarest stable metal found in the earth's crust at just 0.7 parts per billion making it about twice as rare as iridium and osmium and over five times rarer than gold! Gleaming white and perfectly made, these rhenium cubes are the only (reasonably) priced density cubes that are heavier than tungsten or gold at a satisfyingly hefty 20.5 grams each, which is just shy of its 21g theoretical density. A beautiful and interesting collectible sure to delight!
