About this 5.18ct natural oval diamond

This 5.18ct natural oval sits in the over five carat band, graded D colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 5201571822. Listed at 2 retailers as of October 29, 2026, with a relatively tight 3% 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.
