About this 1.03ct lab-grown oval diamond

This 1.03ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG729571247 or 729571247. Listed at 24 retailers as of October 27, 2026, with prices from £188 to £1,440, a £1,252 spread on the same certified stone. Queensmith lists it at £1,440. 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.
