This 1.5ct lab-grown oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG836633573 or 836633573. Listed at 12 retailers as of November 1, 2026, with prices from £173 to £858, a £685 spread on the same certified stone. MOH London lists it at £858. 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.
