About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2427827840. Listed at 7 retailers as of October 29, 2026, with prices from $5,192 to $10,522, a $5,331 spread on the same certified stone. MOH London lists it at $10,522. 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.
