This 0.55ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG588367937 or 588367937. Listed at 15 retailers as of October 26, 2026, with prices from £91 to £846, a £755 spread on the same certified stone. MOH London lists it at £846. 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.
