This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG549202330 or 549202330. Listed at 17 retailers as of October 30, 2026, with prices from £222 to £1,493, a £1,271 spread on the same certified stone. Brilliant Earth lists it at £1,493. 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.
