About this 1.04ct lab-grown cushion diamond

This 1.04ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818613806 or 818613806. Listed at 14 retailers as of October 31, 2026, with prices from €276 to €1,656, a €1,380 spread on the same certified stone. Brilliant Earth lists it at €1,656. 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.
