This 1.62ct 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 standard cut grade and certified by IGI LG607349390 or 607349390. Listed at 7 retailers as of November 1, 2026, with prices from £203 to £1,721, a £1,519 spread on the same certified stone. Do Amore Diamonds lists it at £1,721. 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.
