The compressive strength and hardness of diamond and various other materials, such as boron nitride, [10] (which has the closely related zincblende structure) is attributed to the diamond cubic structure. Example of a diamond cubic truss system for resisting compression. Similarly, truss systems that follow the diamond cubic geometry have a ...
Perfect for storing a weekend’s worth of jewelry, Calpak created a cute and compact organizer, complete with an earring card, snap tabs, and a drawstring pocket. Rating: 4.8 out of 5 stars
Logo used since 2010. Diamonique is the brand name used by television shopping network QVC for their cubic zirconia simulated colorless diamond, simulated colored diamond, and simulated colored gemstone jewelry (cubic zirconia is a common type of gemstone substitute). [1]
Diamonds crystallize in the diamond cubic crystal system (space group Fd 3 m) and consist of tetrahedrally, covalently bonded carbon atoms. A second form called lonsdaleite, with hexagonal symmetry, has also been found, but it is extremely rare and forms only in meteorites or in laboratory synthesis. The local environment of each atom is ...
A diamond simulant, diamond imitation or imitation diamond is an object or material with gemological characteristics similar to those of a diamond. Simulants are distinct from synthetic diamonds , which are actual diamonds exhibiting the same material properties as natural diamonds.
Moissanite was introduced to the jewelry market as a diamond alternative in 1998 after Charles & Colvard (formerly known as C3 Inc.) received patents to create and market lab-grown silicon carbide gemstones, becoming the first firm to do so. By 2018 all patents on the original process world-wide had expired.
Cubic boron nitride adopts a sphalerite crystal structure, which can be constructed by replacing every two carbon atoms in diamond with one boron atom and one nitrogen atom. The short B-N (1.57 Å) bond is close to the diamond C-C bond length (1.54 Å), that results in strong covalent bonding between atoms in the same fashion as in diamond.
The DiamondTouch table is a multi-touch, interactive PC interface product from Circle Twelve Inc.It is a human interface device that has the capability of allowing multiple people to interact simultaneously while identifying which person is touching where. [1]
