About this 6.51ct lab-grown radiant diamond

This 6.51ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG800623080 or 800623080. Listed at a single retailer as of October 31, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
