About this 1.9ct lab-grown cushion diamond

This 1.9ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG839684866 or 839684866. Listed at 16 retailers as of October 29, 2026, with prices from $1,978 to $8,025, a $6,047 spread on the same certified stone. Taylor and Hart lists it at $8,025. 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.
