This 1.91ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG550246689 or 550246689. Listed at 3 retailers as of October 31, 2026, with prices from £949 to £1,970, a £1,021 spread on the same certified stone. Do Amore Diamonds lists it at £1,970. 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.
