About this 2.85ct lab-grown cushion diamond

This 2.85ct 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 stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of October 30, 2026, with prices from $4,336 to $23,344, a $19,009 spread on the same certified stone. Blue Nile lists it at $23,344. 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.
