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 VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG589313372 or 589313372. Listed at 6 retailers as of November 1, 2026, with prices from £216 to £748, a £532 spread on the same certified stone. MOH London lists it at £748. 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.
