About this 2.51ct lab-grown cushion diamond

This 2.51ct lab-grown cushion sits in the two to three carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG830637403 or 830637403. Listed at 9 retailers as of November 1, 2026, with prices from €584 to €2,236, a €1,652 spread on the same certified stone. MOH London lists it at €2,236. 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.
