Description from the seller

Rough diamond ring / new

Set in 925 sterling silver

Total weight: 10.25 ct / 2.05 g

9.5 mm x 7.2 mm

New and unworn

Ring size:

U 51 - 52 (sits exactly between)
UK K 1/2 - L 1/2
US 5.9
FR 11 - 12
Inner diameter: 16.35 mm

Diamond is the cubic modification of carbon and, as a naturally occurring solid, a mineral from the mineral class of the elements. Diamond usually forms octahedral crystals, often with curved and striated faces. Other observed shapes include tetrahedra, dodecahedra, and cubes. The crystals are transparent, colorless, or colored green, yellow, brown, and less commonly orange, blue, pink, red, or gray to black due to impurities (e.g., nitrogen or boron) or lattice defects.

Diamond is the hardest natural substance. On the Mohs scale it has a hardness of 10. Its grinding hardness according to the Roziwal (also absolute hardness) is 140 times greater than that of corundum. The hardness of the diamond, however, varies in different crystallographic directions (anisotropy). This makes it possible to grind diamond with diamond. In the diamond powder used for this purpose, the crystals are present in every orientation (statistical isotropy), so the hardest among them always act on the body to be ground.

Diamond is optically isotropic with a high refractive index and high dispersion. It shows fluorescence and phosphorescence and is triboelectric. It has the highest thermal conductivity of all known minerals.
