About this 1.6ct lab-grown cushion diamond

This 1.6ct 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 LG783632710 or 783632710. Listed at 13 retailers as of October 26, 2026, with prices from £275 to £1,273, a £998 spread on the same certified stone. MOH London lists it at £1,273. 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.
