About this 1.64ct lab-grown cushion diamond

This 1.64ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2494454216. Listed at 20 retailers as of October 31, 2026, with a 327% 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.
