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) and certified by GIA. Listed at 2 retailers as of October 29, 2026, with a relatively tight 4% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
