About this 4.45ct lab-grown cushion diamond

This 4.45ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG728565328 or 728565328. Listed at 18 retailers as of November 1, 2026, with a 361% 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.
