Significant crystals of diamond are beneficial gemstones. The crystal has other appealing properties; it's the highest audio velocity of any stable and is the greatest conductor of heat. Other than diamond, the other common kind of carbon is graphite, and that is a layered substance. Every single carbon atom has 3 coplanar in close proximity to neighbours, forming an arrangement called the honeycomb lattice. Three-dimensional graphite crystals are obtained by stacking related layers.
