This 0.37ct lab-grown round sits in the sub-half-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG578320585 or 578320585. Listed at 3 retailers as of October 31, 2026, with prices from £172 to £812, a £641 spread on the same certified stone. MOH London lists it at £812. 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.
