About this 1.23ct natural princess diamond

This 1.23ct natural princess sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231721589. Listed at 18 retailers as of November 4, 2026, with prices from $1,771 to $4,050, a $2,278 spread on the same certified stone. MOH London lists it at $4,050. 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.
