A new technique grows lab diamonds without high pressure, which could revolutionize the gem industry with a sustainable and efficient process. Scientists Figured Out the Revolutionary Trick for ...
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 ...

Carbonado, commonly known as black diamond, is one of the toughest forms of natural diamond. It is an impure, high-density, micro-porous form of polycrystalline diamond consisting of diamond, graphite , and amorphous carbon , with minor crystalline precipitates filling pores and occasional reduced metal inclusions.

It was cut to 1.09 carats (220 mg) in 1997, and graded a "perfect" 0/0/0 by the American Gem Society (AGS) in 1998 and graded perfect by the Gemological Institute of America, making it the first diamond from Arkansas to receive such an AGS grading. The diamond is considered one-in-a-billion, according to Peter Yantzer, the AGS Laboratory Director.
An animation with scratched figures and hand-painted sections. Drawn-on-film animation, also known as direct animation or animation without camera, is an animation technique where footage is produced by creating the images directly on film stock, as opposed to any other form of animation where the images or objects are photographed frame by frame with an animation camera.
Diamonds with higher color grades are rarer, in higher demand, and therefore more expensive, than lower color grades. Oddly enough, diamonds graded Z are also rare, and the bright yellow color is also highly valued. Diamonds graded D–F are considered "colorless", G–J are considered "near-colorless", K–M are "slightly colored".
A diamond's panorama is three-dimensional. Although diamonds are highly symmetrical, light can enter a diamond from many directions and many angles. This factor further highlights the need to reevaluate Tolkowsky's results, and to recalculate the effects of a diamond's proportions on its appearance aspects. ...
