This 0.62ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG618494378 or 618494378. Listed at 6 retailers as of October 29, 2026, with prices from £106 to £639, a £533 spread on the same certified stone. MOH London lists it at £639. 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.
