This 1.02ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG669420707 or 669420707. Listed at 30 retailers as of October 30, 2026, with prices from £136 to £1,306, a £1,170 spread on the same certified stone. Do Amore Diamonds lists it at £1,306. 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.
