About this 2.51ct lab-grown cushion diamond

This 2.51ct lab-grown cushion sits in the two to three carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799608885 or 799608885. Listed at 15 retailers as of October 30, 2026, with prices from €714 to €2,940, a €2,225 spread on the same certified stone. MOH London lists it at €2,940. 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.
