This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG851653367 or 851653367. Listed at 9 retailers as of November 2, 2026, with prices from $105 to $957, a $852 spread on the same certified stone. MOH London lists it at $957. 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.
