About this 1.01ct lab-grown radiant diamond

This 1.01ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG828666742 or 828666742. Listed at 3 retailers as of November 1, 2026, with prices from £364 to £1,759, a £1,395 spread on the same certified stone. Do Amore Diamonds lists it at £1,759. 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.
