Each Rhenium cube is machined with precision to 10x10x10mm (0.39in) for 1 cm3 and highly polished by hand for hours to reach a mirror finish. Laser engraved! This is an heirloom piece that will last forever.
Made of high purity 99.99% Rhenium sheets, our Rhenium cube is about 20.5g/cm3. (The Rhenium sheet could reach the theoretical density (21.04g/cm3) with the hot isostatic pressing process, but the cost is surprisingly high.)
Rhenium is a chemical element with the symbol Re and atomic number 75. Here are some interesting facts:
