About this 0.81ct lab-grown cushion diamond

This 0.81ct 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 LG816658195 or 816658195. Listed at 11 retailers as of October 30, 2026, with prices from €380 to €1,729, a €1,348 spread on the same certified stone. Diamond Exchange Canada lists it at €1,729. 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.
