This 2.89ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754594819 or 754594819. Listed at 21 retailers as of October 28, 2026, with prices from $1,654 to $7,970, a $6,316 spread on the same certified stone. Brilliant Earth lists it at $7,970. 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.
