Flawless Man-Made Diamonds
Perfect single-crystal diamonds of more than two carats(the average engagement ring is less than a carat) churned out in a day. Scientists create the gemstones using a process called chemical vapor deposition (CVD), which grows diamond crystals one carbon atom at a time.The jewelry industry has shown great interest in ersatz versions of the 45-carat Hope diamond, but other uses could prove more lucrative. Using CVD, scientists will be able to cheaply mass-produce diamond semiconductors that are hundreds of times as powerful as their silicon counterparts.

Diamond is one of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light make it useful for industrial applications and jewelry (the other equally well known allotrope is graphite). Diamonds are specifically renowned as a mineral with superlative physical qualities - they make excellent abrasives because they can only be scratched by other diamonds, which also means they hold a polish extremely well and retain luster. About 130 million carats (26,000 kg) are mined annually, with a total value of nearly USD $9 billion.
Small Loose Diamonds
Small loose diamonds can have more than one dozen different shapes. The following article mentions some of the more common shapes.

Any of those diamonds can have clarity and polish as great as, or greater, than the clarity and polish on any of the certified and geometrically shaped diamonds mentioned in the following article. In addition, any of those diamonds can have a carat weight that lifts it into the category of top quality diamon
