About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 801637883. Listed at 16 retailers as of November 5, 2026, with prices from £1,768 to £4,150, a £2,382 spread on the same certified stone. NZ Jewellers lists it at £4,150. 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.
