About this 1.51ct natural pear diamond

This 1.51ct natural pear sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 801637787. Listed at 17 retailers as of October 30, 2026, with prices from £2,070 to £4,026, a £1,956 spread on the same certified stone. NZ Jewellers lists it at £4,026. 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.
