This 1.57ct lab-grown radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG772610375 or 772610375. Listed at 15 retailers as of October 27, 2026, with prices from £150 to £1,054, a £904 spread on the same certified stone. Brilliant Earth lists it at £1,054. 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.
