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 H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG754510428 or 754510428. Listed at 15 retailers as of October 31, 2026, with prices from €146 to €904, a €758 spread on the same certified stone. Brilliant Earth lists it at €904. 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.
