Lonsdaleite static press or using explosives. It has also been produced by chemical vapor deposition, and also by the thermal decomposition of a polymer, poly(hydridocarbyne), at atmospheric pressure, under argon atmosphere, at . It is translucent, brownish-yellow, and has an index of refraction of 2.40 to 2.41 and a specific gravity of 3.2 to 3.3. Its hardness is theoretically superior to that of cubic diamond (up to 58% more), according to computational simulations, but natural specimens exhibited somewhat lower hardness through a large range of values (from 7 to 8 on Mohs hardness scale). The cause is speculated as being due
Mohs surgery 2004 and 2014. In a sample of 100 Mohs surgeries, the cost ranged from US$474 to USUS$7,594, with the higher costs for hospital-based physicians. In 2010, hospital-based dermatologists who did Mohs surgery were paid US$586,083, according to Becker's Hospital Review. When the surgery is performed in different steps by different specialists, each specialist can bill for his or her own procedure, such as the surgery itself, closing the wound, anesthesiology, and facilities fees. This can total more than US$25,000 for a single procedure. Originally, Mohs used a chemical paste (an escharotic agent) to cauterize and kill the tissue. It was
