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 October 30, 2026, with prices from $312 to $1,836, a $1,524 spread on the same certified stone. Diamond Exchange Canada lists it at $1,836. 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.
