About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG671491278 or 671491278. Listed at 21 retailers as of October 29, 2026, with prices from £164 to £938, a £774 spread on the same certified stone. Reve Diamonds lists it at £938. 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.
