This 1.56ct lab-grown radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG825631424 or 825631424. Listed at 19 retailers as of October 30, 2026, with prices from £137 to £873, a £737 spread on the same certified stone. Brilliant Earth lists it at £873. 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.
