This 0.57ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407941405 or 407941405. Listed at 11 retailers as of November 1, 2026, with prices from €271 to €1,349, a €1,078 spread on the same certified stone. MOH London lists it at €1,349. 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.
