About this 0.9ct lab-grown cushion diamond

This 0.9ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG749508912 or 749508912. Listed at 21 retailers as of November 3, 2026, with prices from $560 to $3,877, a $3,317 spread on the same certified stone. Do Amore Diamonds lists it at $3,877. 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.
