About this 5.21ct lab-grown round diamond

This 5.21ct lab-grown round sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 5221403051. Listed at 15 retailers as of October 29, 2026, with a 268% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
