About this 2.9ct lab-grown cushion diamond

This 2.9ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG836603096 or 836603096. Listed at 11 retailers as of October 29, 2026, with a 302% 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.
