A diamond is a very valuable gemstone with remarkable physical characteristics: it has the highest hardness and thermal conductivity of any bulk material and a relatively high optical dispersion which results in its characteristic luster.
For Christmas, in 1996, Fred and George Weasley offered their mother a brand-new midnight blue witch's hat glittering with what looked like tiny starlike diamonds. The downstairs windows of Malfoy Manor were diamond-paned. Diamonds were among the gems set into Muriel's tiara, as well as moonstones.
