About this 0.4ct natural princess diamond

This 0.4ct natural princess sits in the sub-half-carat band, graded G 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 5506858844. Listed at 7 retailers as of November 5, 2026, with prices from £180 to £961, a £781 spread on the same certified stone. NZ Jewellers lists it at £961. 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.
