About this 10.55ct lab-grown cushion diamond

This 10.55ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG783664101 or 783664101. Listed at 9 retailers as of October 30, 2026, with a 217% 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.
