Lonsdaleite is one of the most recent and rare materials researched by the scientists and it is characterized by amazing proprieties. One of its main characteristics is to be correlated with diamond, as far as the chemical composition and crystal structure are concerned, and with meteorites, because of its best-known formation process. Thanks to those proprieties, recently a material attractively called “Lonsdaleite Diamond” or “Stars Diamond” started to circulate in some gemstones and precious minerals markets. The purpose of this group is to bring up some topics and reveal Lonsdaleite, what it is, what it studies and what can actually be found in the trade. ////—I have a diamond of 263 grams Show More
