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 1236510867. Listed at 6 retailers as of November 4, 2026, with prices from £418 to £790, a £371 spread on the same certified stone. MOH London lists it at £790. 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.
