About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556890547. Listed at 19 retailers as of November 5, 2026, with prices from £2,973 to £6,557, a £3,584 spread on the same certified stone. NZ Jewellers lists it at £6,557. 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.
