This 0.39ct lab-grown round sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG693552450 or 693552450. Listed at 11 retailers as of November 1, 2026, with prices from £49 to £451, a £402 spread on the same certified stone. MOH London lists it at £451. 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.
