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 801638932. Listed at 16 retailers as of October 27, 2026, with prices from £1,701 to £4,073, a £2,372 spread on the same certified stone. NZ Jewellers lists it at £4,073. 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.
