About this 0.99ct lab-grown oval diamond

This 0.99ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844661240 or 844661240. Listed at 10 retailers as of October 28, 2026, with prices from £330 to £999, a £669 spread on the same certified stone. Brilliant Earth lists it at £999. 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.
