The Elizabeth Taylor Diamond, also known as the Krupp Diamond, is a Type IIa Asscher cut diamond weighing 33.19 carats. It sold in 2011 for $8.8 million. The world's largest gem-quality rough diamond, The Cullinan Diamond, is a Type IIa diamond. The rough diamond weighed 3,106.75 carats. It was eventually cut into 9 large stones (above) and ...
Various growth processes may be used. For example, crystalline or polycrystalline diamond can be grown using chemical vapor deposition (CVD), plasma enhanced chemical vapor deposition (PECVD), hot wire diamond growth, or the like. Amorphous diamond can be grown using pulsed laser deposition (PLD) or other processes known in the art.
11.46x11.04x0.51 mm single-crystal diamond plate was cut from a synthetic diamond of IIb type (crystal weight is 10.87 ct) perpendicularly to [111]. This diamond was grown on (111) seed. Except predominant {111} facets, there were different facets of {100}, {110}, {113} and {115} orientations in the diamond.

This causes a different cost for each type of cut. For example you can cut your rough for 1ct Round diamond, or you can have approximately only 0.65ct Oval from the same rough. That's why pricing is different from one type of cut to another.
CVD is a newer technology and the preferred process to produce a quality, genuine diamond. Oui only uses lab diamonds that are grown using the CVD process. It is generally considered to take about a month to grow a 1ct CVD diamond, although growth periods vary individually for each diamond.
2021-11-1 · The interface can be manipulated by changing the surface energy, chemistry, and topography of the Titanium-based implant. Recently, polycrystalline diamond (PCD) has emerged as an exciting coating material for 3D printed titanium scaffolds showing enhanced mammalian cell functions while inhibiting bacterial attachment in vitro.
