About this 3.11ct lab-grown cushion diamond

This 3.11ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG607309865 or 607309865. Listed at 10 retailers as of October 31, 2026, with prices from $658 to $4,040, a $3,382 spread on the same certified stone. Do Amore Diamonds lists it at $4,040. 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.
