About this 10.05ct lab-grown cushion diamond

This 10.05ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840638389 or 840638389. Listed at 9 retailers as of October 30, 2026, with a 185% 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.
