About this 1.26ct lab-grown round diamond

This 1.26ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG766644661 or 766644661. Listed at 10 retailers as of October 25, 2026, with prices from €186 to €875, a €689 spread on the same certified stone. MOH London lists it at €875. 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.
