About this 0.89ct lab-grown cushion diamond

This 0.89ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799607979 or 799607979. Listed at 12 retailers as of November 1, 2026, with prices from $914 to $5,741, a $4,827 spread on the same certified stone. MOH London lists it at $5,741. 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.
