About this 0.66ct natural princess diamond

This 0.66ct natural princess sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1232583121. Listed at 17 retailers as of November 1, 2026, with prices from £391 to £1,218, a £827 spread on the same certified stone. Diamond Exchange Canada lists it at £1,218. 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.
