Description from the seller
Rough diamond pendant / new
Set in 925 sterling silver
Includes leather cord
Weight: 1.14 g (weighed without the leather cord)
11.0 mm x 8.2 mm x 6.2 mm
New and unworn
Diamond is the cubic form of carbon and, as a naturally occurring solid, a mineral belonging to the mineral class of native elements. Diamonds usually form octahedral crystals, often with curved and striated faces. Other observed forms include tetrahedra, dodecahedra, and cubes. The crystals are transparent and colorless, or colored green, yellow, or brown—and more rarely orange, blue, pink, red, or gray to black—by impurities (e.g. nitrogen or boron) or crystal lattice defects.
Diamond is the hardest naturally occurring material. On the Mohs scale of hardness, it has a hardness of 10. Its grinding hardness according to Rosiwal (also called absolute hardness) is 140 times greater than that of corundum. However, a diamond's hardness varies in different crystal directions (anisotropy). This makes it possible to grind diamond with diamond. In the diamond powder used for this purpose, the crystals are oriented in every direction (statistical isotropy), so the hardest crystals are always among those acting on the material being ground.
Diamond is optically isotropic, with high refractive index and high dispersion. It exhibits fluorescence and phosphorescence and is triboelectric. It has the highest thermal conductivity of any known mineral.
