About this 8.51ct lab-grown radiant diamond

This 8.51ct 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 stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of November 2, 2026, with prices from £3,716 to £4,679, a £963 spread on the same certified stone. Diamond Exchange Canada lists it at £4,679. 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.
