About this 1.08ct lab-grown oval diamond

This 1.08ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG627454027 or 627454027. Listed at 3 retailers as of November 4, 2026, with prices from £847 to £1,493, a £646 spread on the same certified stone. Kay Jewelers lists it at £1,493. 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.
