About this 1.2ct lab-grown round diamond

This 1.2ct lab-grown round sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG800681231 or 800681231. Listed at 4 retailers as of November 1, 2026, with prices from €323 to €859, a €537 spread on the same certified stone. MOH London lists it at €859. 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.
