This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 737519558. Listed at 16 retailers as of October 30, 2026, with prices from £4,452 to £8,537, a £4,085 spread on the same certified stone. NZ Jewellers lists it at £8,537. 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.
