About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1518770488. Listed at 6 retailers as of November 4, 2026, with prices from $4,865 to $9,955, a $5,090 spread on the same certified stone. MOH London lists it at $9,955. 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.
