About this 1.68ct lab-grown princess diamond

This 1.68ct lab-grown princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3445525204. Listed at 9 retailers as of November 1, 2026, with prices from £299 to £1,502, a £1,204 spread on the same certified stone. MOH London lists it at £1,502. 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.
