Diamonds are mainly irradiated to become blue-green or green, although other colors are possible. [29] When light-to-medium-yellow diamonds are treated with gamma rays they may become green; with a high-energy electron beam, blue. [23] The difference in results may be caused by local heating of the stones, which occurs when the latter method is ...
These high-energy particles physically alter the diamond's crystal lattice, knocking carbon atoms out of place and producing color centers. Irradiated diamonds are all some shade of green, black, or blue after treatment, but most are annealed to further modify their color into bright shades of yellow, orange, brown, or pink. The annealing ...
Crystal healing is a pseudoscientific alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opal. Despite the common use of the term "crystal", many popular stones used in crystal healing, such as obsidian, are not technically crystals .
Pure (type IIa) diamond can be colored pink, red, or, brown owing to structural anomalies arising through plastic deformation during crystal growth; [20] these diamonds are rare (1.8% of gem diamonds), but constitute a large percentage of Australian diamonds. Type IIb diamonds, which account for ~0.1% of gem diamonds, are usually a steely blue ...
Waning demand for natural diamonds has helped lift De Beers's inventory to $2 billion, the most since the 2008 financial crash, according to the Financial Times. In fact, the value of the diamond ...
The nitrogen vacancy defect in diamond consists of a single substitutional nitrogen atom (replacing one carbon atom) and an adjacent gap, or vacancy, in the lattice where normally a carbon atom would be located. A nitrogen vacancy centre in the diamond lattice, viewed along the [100] axis. Carbon atoms (grey) make up the bulk diamond crystal.
January's full moon may have you howling! Nicknamed the Wolf Moon, this month's lunation will reach peak fullness at 2:27 p.m. PT on Jan. 13, marking the first full moon of 2025 and rising two ...
When “The Room Next Door” premiered at the Venice Film Festival in early September, the rapturous audience gave director Pedro Almodóvar and his two stars, Tilda Swinton and Julianne Moore, a ...
