About this 4.54ct lab-grown cushion diamond

This 4.54ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG778690858 or 778690858. Listed at 16 retailers as of October 30, 2026, with a 412% 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.
