About this 0.77ct lab-grown cushion diamond

This 0.77ct 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 LG816662563 or 816662563. Listed at 18 retailers as of November 2, 2026, with prices from $443 to $2,617, a $2,173 spread on the same certified stone. Diamond Exchange Canada lists it at $2,617. 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.
