About this 1.21ct lab-grown princess diamond

This 1.21ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG848666527 or 848666527. Listed at 13 retailers as of November 4, 2026, with prices from £150 to £840, a £690 spread on the same certified stone. Reve Diamonds lists it at £840. 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.
