About this 1.69ct lab-grown round diamond

This 1.69ct lab-grown round sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG621487852 or 621487852. Listed at 14 retailers as of October 29, 2026, with prices from £342 to £913, a £571 spread on the same certified stone. MOH London lists it at £913. 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.
