About this 1.03ct lab-grown oval diamond

This 1.03ct lab-grown oval sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG731504463 or 731504463. Listed at 13 retailers as of November 2, 2026, with prices from £114 to £660, a £547 spread on the same certified stone. MOH London lists it at £660. 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.
