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 LG602388107 or 602388107. Listed at 7 retailers as of October 31, 2026, with prices from $730 to $3,890, a $3,160 spread on the same certified stone. Do Amore Diamonds lists it at $3,890. 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.
