About this 4.5ct lab-grown cushion diamond

This 4.5ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841611636 or 841611636. Listed at 9 retailers as of October 28, 2026, with a 126% 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.
