About this 1.99ct lab-grown cushion diamond

This 1.99ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG826630966 or 826630966. Listed at 18 retailers as of November 3, 2026, with a 511% 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.
