About this 3.03ct natural princess diamond

This 3.03ct natural princess sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2428427417. Listed at 21 retailers as of November 2, 2026, with prices from £11,620 to £20,978, a £9,358 spread on the same certified stone. MOH London lists it at £20,978. 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.
