About this 1.18ct lab-grown oval diamond

This 1.18ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG838640817 or 838640817. Listed at 3 retailers as of October 29, 2026, with prices from £586 to £935, a £349 spread on the same certified stone. MOH London lists it at £935. 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.
