About this 1.16ct lab-grown oval diamond

This 1.16ct 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 LG836619361 or 836619361. Listed at 21 retailers as of October 29, 2026, with prices from £143 to £1,321, a £1,178 spread on the same certified stone. Brilliant Earth lists it at £1,321. 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.
