About this 20.42ct natural oval diamond

This 20.42ct natural oval sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5221963351. Listed at 10 retailers as of October 27, 2026, with prices from $1,631,612 to $2,039,516, a $407,904 spread on the same certified stone. Aurelinne lists it at $2,039,516. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
