About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821650603 or 821650603. Listed at 15 retailers as of October 25, 2026, with a 338% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
