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 standard cut grade and certified by IGI LG831696647 or 831696647. Listed at 15 retailers as of November 1, 2026, with prices from €443 to €1,505, a €1,062 spread on the same certified stone. Helzberg Diamonds lists it at €1,505. 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.
