About this 3ct natural princess diamond

This 3ct natural princess sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6402980223. Listed at 18 retailers as of October 30, 2026, with prices from £16,546 to £30,821, a £14,275 spread on the same certified stone. MOH London lists it at £30,821. 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.
