This 1.64ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG607349476 or 607349476. Listed at 6 retailers as of October 27, 2026, with prices from £178 to £1,427, a £1,249 spread on the same certified stone. Do Amore Diamonds lists it at £1,427. 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.
