About this 1.37ct lab-grown cushion diamond

This 1.37ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831698113 or 831698113. Listed at 15 retailers as of November 4, 2026, with prices from $870 to $4,269, a $3,399 spread on the same certified stone. Brilliant Earth lists it at $4,269. 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.
