About this 4.3ct lab-grown cushion diamond

This 4.3ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG784646949 or 784646949. Listed at 10 retailers as of October 28, 2026, with prices from $4,122 to $26,120, a $21,998 spread on the same certified stone. Do Amore Diamonds lists it at $26,120. 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.
