About this 2.51ct natural princess diamond

This 2.51ct natural princess sits in the two to three carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5563550205. Listed at 15 retailers as of October 30, 2026, with prices from $28,161 to $52,571, a $24,410 spread on the same certified stone. With Clarity lists it at $52,571. 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.
