This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830620288 or 830620288. Listed at 14 retailers as of November 4, 2026, with prices from €406 to €2,161, a €1,754 spread on the same certified stone. Helzberg Diamonds lists it at €2,161. 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.
