About this 1.26ct lab-grown princess diamond

This 1.26ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799669189 or 799669189. Listed at 7 retailers as of October 29, 2026, with prices from £458 to £1,133, a £674 spread on the same certified stone. MOH London lists it at £1,133. 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.
