Collecting elements starts off cheap with a bit of aluminum here, a little copper wire there and a lead sinker you found in the basement. Then, as each new slot in your set gets filled in the challenge of finding the next and its price goes up. Then when it gets to the platinum group the price goes waaaay up. Either that or you settle for tiny samples. And this is rhodium, the rarest and most expensive metal ever sold as bullion, currently sitting at an astronomical $10,000+ an ounce(!) Many would say that its exorbitant cost is still undervalued relative to its rarity!

Each cube holds a one gram sample of 99.95% pure rhodium metal as scattered flakes that sparkle like jewelry. Each cube comes in optical clarity Lucite acrylic worthy of a museum display! Larger samples are available on request.
