About this 1.16ct lab-grown oval diamond

This 1.16ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG598394023 or 598394023. Listed at 3 retailers as of October 28, 2026, with prices from £826 to £1,081, a £255 spread on the same certified stone. Kay Jewelers lists it at £1,081. 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.
