About this 1.65ct lab-grown cushion diamond

This 1.65ct 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 standard cut grade and certified by IGI LG619445814 or 619445814. Listed at 6 retailers as of October 30, 2026, with prices from £335 to £926, a £591 spread on the same certified stone. MOH London lists it at £926. 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.
