About this 1.55ct natural princess diamond

This 1.55ct natural princess sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 12978224. Listed at 5 retailers as of October 30, 2026, with prices from £3,046 to £4,023, a £977 spread on the same certified stone. Jared lists it at £4,023. 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.
