About this 2.51ct lab-grown radiant diamond

This 2.51ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6501487009. Listed at 21 retailers as of October 26, 2026, with prices from €533 to €2,877, a €2,344 spread on the same certified stone. MOH London lists it at €2,877. 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.
