About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG414096670 or 414096670. Listed at 5 retailers as of October 26, 2026, with prices from £858 to £1,644, a £785 spread on the same certified stone. MOH London lists it at £1,644. 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.
