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 VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG659425001 or 659425001. Listed at 22 retailers as of November 2, 2026, with prices from £136 to £865, a £729 spread on the same certified stone. Brilliant Earth lists it at £865. 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.
