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 29, 2026, with prices from $3,479 to $18,730, a $15,252 spread on the same certified stone. Blue Nile lists it at $18,730. 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.
