About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG651420687 or 651420687. Listed at 4 retailers as of October 30, 2026, with prices from $1,730 to $3,520, a $1,790 spread on the same certified stone. Kay Jewelers lists it at $3,520. 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.
