About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG12466816 or 12466816. Listed at 5 retailers as of October 29, 2026, with prices from €226 to €1,180, a €954 spread on the same certified stone. MOH London lists it at €1,180. 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.
