About this 0.4ct natural princess diamond

This 0.4ct natural princess sits in the sub-half-carat band, graded H 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 6561317600. Listed at 3 retailers as of November 1, 2026, with prices from £246 to £338, a £92 spread on the same certified stone. 77 Diamonds lists it at £338. 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.
