About this 1.27ct lab-grown cushion diamond

This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833665771 or 833665771. Listed at 17 retailers as of November 6, 2026, with prices from €341 to €1,953, a €1,611 spread on the same certified stone. Brilliant Earth lists it at €1,953. 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.
