About this 0.3ct natural princess diamond

This 0.3ct natural princess sits in the sub-half-carat band, graded J 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 1563394488. Listed at 3 retailers as of November 1, 2026, with prices from £143 to £208, a £65 spread on the same certified stone. Rare Carat lists it at £208. 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.
