About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 803628990. Listed at 16 retailers as of October 27, 2026, with prices from £3,714 to £7,122, a £3,408 spread on the same certified stone. NZ Jewellers lists it at £7,122. 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.
