This 0.53ct lab-grown oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407915171 or 407915171. Listed at 10 retailers as of October 29, 2026, with prices from £236 to £1,178, a £942 spread on the same certified stone. MOH London lists it at £1,178. 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.
