About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 656474494. Listed at 17 retailers as of October 30, 2026, with prices from £1,366 to £3,821, a £2,455 spread on the same certified stone. NZ Jewellers lists it at £3,821. 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.
