About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 662419811. Listed at 17 retailers as of October 27, 2026, with prices from £3,047 to £6,461, a £3,414 spread on the same certified stone. NZ Jewellers lists it at £6,461. 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.
