About this 20.66ct natural oval diamond
This 20.66ct natural oval sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
