About this 1.29ct lab-grown radiant diamond

This 1.29ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 313081015. Listed at 12 retailers as of November 4, 2026, with prices from £120 to £764, a £645 spread on the same certified stone. MOH London lists it at £764. 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.
