About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 653410934. Listed at 15 retailers as of October 27, 2026, with prices from £2,207 to £4,331, a £2,125 spread on the same certified stone. NZ Jewellers lists it at £4,331. 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.
