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 5, 2026, with prices from $553 to $3,265, a $2,712 spread on the same certified stone. Diamond Exchange Canada lists it at $3,265. 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.
