About this 1.28ct natural princess diamond

This 1.28ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 720508545. Listed at 14 retailers as of October 30, 2026, with prices from £2,312 to £4,538, a £2,226 spread on the same certified stone. NZ Jewellers lists it at £4,538. 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.
