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 ...
Since the 1950s, techniques can produce gem-quality diamonds of essentially any desired chemistry in sizes up to about 1cm. [6] Although some manufacturers do label their synthetic diamonds with serial numbers, there is no guarantee that a given diamond is not man made, although sometimes an unnatural chemical composition or pattern of flaws may suggest a diamond is synthetic.
In the paradox of value, it is a contradiction that it is cheaper than diamonds, despite diamonds not having such an importance to life. The paradox of value, also known as the diamond–water paradox, is the paradox that, although water is on the whole more useful in terms of survival than diamonds, diamonds command a higher price in the market.
It is impossible to tell the difference between newly mined and polished diamonds and recycled diamonds. As a result, the price should be similar. A recycled diamond might be in excellent condition, though quite possibly have a dated cut or look. As such, a lot of recycled diamonds go through a re-cutting or re-polishing process to make them ...
In order to be considered for use as a diamond simulant, a material must possess certain diamond-like properties. The most advanced artificial simulants have properties which closely approach diamond, but all simulants have one or more features that clearly and (for those familiar with diamond) easily differentiate them from diamond.
“I didn’t actually see the person in question. Apparently she hid in a lavatory all the way at the rear of the aircraft when we departed JFK,” Jackson said. “The first announcement to ...
UConn had a last look at the basket following a timeout with 5.9 seconds remaining. But Hassan Diarra's go-ahead 3-point attempt clanged off the rim just before the final buzzer sounded.
Releasing the bears into the wild. The bears are taken to location where the wildlife agency has previously observed "great success in not seeing the bears turn back up as conflict bears or roadkill."
