HRD Antwerp recently graded a 3.09 carat diamond thus once again illustrating that diamond growers will be able to continue growing the size of diamonds they produce. This latest development also indicates that lab-grown diamonds are becoming increasingly popular.
The 3.09 carat diamond has been grown using the chemical vapor deposition technique, also called CVD. The CVD technique is a special method in which diamonds are created in specially developed growing chamber using a carbon-rich gas. In this technique, diamonds are grown without the use of nitrogen. Thus these diamonds are always categorized as Type IIa and Type IIb gemstones
According to the reports from the HRD lab, this particular 3.09 carat stone is categorized as a brilliant-cut diamond with a color grade of slightly tinted white (I) and with clarity of VS2.
Late last year, Pure Grown Diamonds had produced the largest, nearly colorless lab-grown diamond weighing 3.04 carats. The diamond came with a price tag of $23,012.
The popularity of lab-grown diamonds is only on the rise in the last few tears. Diamonds growers now have improved techniques and are able to produce white diamonds, almost flawlessly. Moreover, mainstream stores have also started selling them.
