About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG602395629 or 602395629. Listed at 15 retailers as of November 4, 2026, with prices from €244 to €1,330, a €1,086 spread on the same certified stone. Taylor and Hart lists it at €1,330. 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.
