About this 3.11ct lab-grown cushion diamond

This 3.11ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799608892 or 799608892. Listed at 13 retailers as of October 29, 2026, with prices from €885 to €3,285, a €2,400 spread on the same certified stone. Brilliant Earth lists it at €3,285. 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.
