About this 2.51ct lab-grown radiant diamond

This 2.51ct lab-grown radiant sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (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 €861 to €2,410, a €1,549 spread on the same certified stone. Diamond Exchange Canada lists it at €2,410. 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.
