About this 3.05ct natural princess diamond

This 3.05ct natural princess sits in the three to five carat band, graded I 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 1558389737. Listed at 13 retailers as of November 4, 2026, with prices from £12,814 to £19,565, a £6,752 spread on the same certified stone. MOH London lists it at £19,565. 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.
