This 1.6ct lab-grown radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG529281908 or 529281908. Listed at 6 retailers as of November 1, 2026, with prices from £223 to £853, a £630 spread on the same certified stone. MOH London lists it at £853. 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.
