This 1.99ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG820604514 or 820604514. Listed at 7 retailers as of October 31, 2026, with prices from £392 to £1,985, a £1,593 spread on the same certified stone. Brilliant Earth lists it at £1,985. 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.
