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 803629129. Listed at 18 retailers as of October 30, 2026, with prices from £2,636 to £5,221, a £2,585 spread on the same certified stone. NZ Jewellers lists it at £5,221. 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.
