About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 813687850. Listed at 16 retailers as of October 30, 2026, with prices from £1,227 to £3,403, a £2,176 spread on the same certified stone. NZ Jewellers lists it at £3,403. 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.
