About this 3ct lab-grown radiant diamond

This 3ct lab-grown radiant sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG512202901 or 512202901. Listed at 14 retailers as of October 29, 2026, with prices from £478 to £2,657, a £2,179 spread on the same certified stone. Brilliant Earth lists it at £2,657. 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.
