This 1.33ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG567369943 or 567369943. Listed at 7 retailers as of November 4, 2026, with prices from £203 to £702, a £499 spread on the same certified stone. MOH London lists it at £702. 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.
