About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG784646404 or 784646404. Listed at 10 retailers as of October 30, 2026, with prices from $528 to $3,814, a $3,286 spread on the same certified stone. Do Amore Diamonds lists it at $3,814. 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.
