About this 1.22ct lab-grown oval diamond

This 1.22ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG551276085 or 551276085. Listed at 2 retailers as of November 1, 2026, with prices from £318 to £808, a £490 spread on the same certified stone. MOH London lists it at £808. 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.
