About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 825619204. Listed at 19 retailers as of October 30, 2026, with prices from £1,239 to £3,433, a £2,195 spread on the same certified stone. NZ Jewellers lists it at £3,433. 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.
