About this 1.91ct lab-grown cushion diamond

This 1.91ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG836603142 or 836603142. Listed at 10 retailers as of October 28, 2026, with prices from $1,229 to $6,363, a $5,134 spread on the same certified stone. Brilliant Earth lists it at $6,363. 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.
