This 0.73ct 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 LG414059517 or 414059517. Listed at 11 retailers as of November 5, 2026, with prices from £344 to £1,894, a £1,550 spread on the same certified stone. MOH London lists it at £1,894. 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.
