This 0.54ct lab-grown oval sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG593372359 or 593372359. Listed at 10 retailers as of November 4, 2026, with prices from £104 to £663, a £559 spread on the same certified stone. MOH London lists it at £663. 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.
