About this 0.8ct lab-grown cushion diamond

This 0.8ct 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 LG799607981 or 799607981. Listed at 12 retailers as of November 3, 2026, with prices from $661 to $3,999, a $3,338 spread on the same certified stone. MOH London lists it at $3,999. 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.
