About this 1.2ct lab-grown oval diamond

This 1.2ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG833684985 or 833684985. Listed at 15 retailers as of October 29, 2026, with prices from £143 to £875, a £732 spread on the same certified stone. Reve Diamonds lists it at £875. 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.
