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. Adherents of the practice claim that these have healing powers, but there is no scientific basis for this claim.
While lab-grown diamonds have flourished among Gen Z, De Beers has found success for grown gems elsewhere. Forget bling, De Beers has found a surprising use for lab-grown diamonds outside of ...
Many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. Another term used is habit, the form the gem is usually found in. [12] For example, diamonds, which have a cubic crystal system, are often found as octahedrons. [13] Gemstones are classified into different groups, species, and varieties.
Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...
The Hindu polymath Varāhamihira's 6th century Brhat Samhit encyclopedic work describes the bright star Canopus, named Agastya (अगस्त्य) in Sanskrit, also the name of the rishi Agastya, "Its huge white waves looked like clouds; its gems looked like stars; its crystals looked like the Moon; and its long bright serpents bearing gems ...
