About this 1.23ct lab-grown cushion diamond

This 1.23ct 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 LG738504423 or 738504423. Listed at 16 retailers as of November 3, 2026, with prices from €397 to €1,718, a €1,321 spread on the same certified stone. MOH London lists it at €1,718. 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.
