About this 1.05ct lab-grown radiant diamond

This 1.05ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG696522926 or 696522926. Listed at 22 retailers as of November 2, 2026, with prices from £165 to £1,550, a £1,385 spread on the same certified stone. Brilliant Earth lists it at £1,550. 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.
