This 1.89ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG616408127 or 616408127. Listed at 5 retailers as of October 26, 2026, with prices from £361 to £1,702, a £1,340 spread on the same certified stone. Jared lists it at £1,702. 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.
