About this 1.65ct lab-grown cushion diamond

This 1.65ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG760504602 or 760504602. Listed at 8 retailers as of November 1, 2026, with a 198% 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.
