About this 0.8ct lab-grown radiant diamond

This 0.8ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG414075893 or 414075893. Listed at 3 retailers as of October 29, 2026, with prices from £219 to £950, a £731 spread on the same certified stone. MOH London lists it at £950. 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.
