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 by ease of hemostasis is weighed against the risk of stopping anticoagulants; and it is generally preferred to continue anticoagulants. Few specialists dispute the cure rate for Mohs, especially pathologists familiar with the procedure. Extensive studies performed by Mohs involving thousands of patients with both fixed tissue and fresh tissue cases have been reported in the literature. Other surgeons repeated the studies with also thousands of cases, with nearly the same results. Clinical 5 year cure rates with Mohs surgery: These are only a small number of cases reported by Mohs, and numerous other articles by other authors have shown
