This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840664669 or 840664669. Listed at 17 retailers as of November 4, 2026, with prices from £169 to £895, a £727 spread on the same certified stone. Reve Diamonds lists it at £895. 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.
