This 1.51ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG839647857 or 839647857. Listed at 11 retailers as of November 5, 2026, with prices from €194 to €1,007, a €812 spread on the same certified stone. MOH London lists it at €1,007. 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.
