About this 6.5ct lab-grown cushion diamond

This 6.5ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799626060 or 799626060. Listed at 12 retailers as of October 31, 2026, with a 220% 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.
