Substantial crystals of diamond are worthwhile gemstones. The crystal has other interesting Attributes; it has the highest sound velocity of any reliable and is the greatest conductor of warmth. Aside from diamond, one other widespread type of carbon is graphite, which happens to be a layered substance. Each individual carbon atom has a few coplanar around neighbours, forming an arrangement known as the honeycomb lattice. 3-dimensional graphite crystals are obtained by stacking similar layers.
