About this 3.15ct lab-grown cushion diamond

This 3.15ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG835649045 or 835649045. Listed at 19 retailers as of October 31, 2026, with a 323% 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.
