This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG557236171 or 557236171. Listed at 12 retailers as of October 31, 2026, with prices from £293 to £1,826, a £1,533 spread on the same certified stone. Do Amore Diamonds lists it at £1,826. 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.
