About this 1.08ct lab-grown princess diamond

This 1.08ct lab-grown princess 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 LG591350836 or 591350836. Listed at 22 retailers as of October 29, 2026, with prices from £172 to £1,292, a £1,120 spread on the same certified stone. Brilliant Earth lists it at £1,292. 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.
