About this 2.05ct lab-grown cushion diamond

This 2.05ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG496117887 or 496117887. Listed at 10 retailers as of November 2, 2026, with a 266% 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.
