This 1.51ct natural pear sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 811694550. Listed at 16 retailers as of November 3, 2026, with prices from £1,536 to £4,133, a £2,597 spread on the same certified stone. NZ Jewellers lists it at £4,133. 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.
