About this 1.03ct lab-grown oval diamond

This 1.03ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG842635031 or 842635031. Listed at 11 retailers as of October 30, 2026, with prices from £188 to £978, a £790 spread on the same certified stone. Do Amore Diamonds lists it at £978. 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.
