About this 1.05ct lab-grown oval diamond

This 1.05ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG726534332 or 726534332. Listed at 24 retailers as of October 27, 2026, with prices from £191 to £1,440, a £1,249 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.
