About this 4.51ct lab-grown cushion diamond

This 4.51ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG787667297 or 787667297. Listed at 8 retailers as of November 1, 2026, with a 196% 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.
