About this 1.2ct lab-grown oval diamond

This 1.2ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG765628893 or 765628893. Listed at 10 retailers as of October 25, 2026, with prices from £304 to £1,226, a £922 spread on the same certified stone. MOH London lists it at £1,226. 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.
