About this 1.2ct lab-grown princess diamond

This 1.2ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6421737549. Listed at 17 retailers as of October 25, 2026, with prices from £224 to £1,113, a £889 spread on the same certified stone. MOH London lists it at £1,113. 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.
