About this 1.84ct lab-grown cushion diamond

This 1.84ct lab-grown cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG633442510 or 633442510. Listed at 4 retailers as of October 31, 2026, with prices from £701 to £963, a £262 spread on the same certified stone. Kay Jewelers lists it at £963. 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.
