About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LGS2G57536 or S2G57536. Listed at 2 retailers as of October 31, 2026, with prices from €930 to €1,607, a €677 spread on the same certified stone. Yorxs lists it at €1,607. 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.
