About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555943977. Listed at 16 retailers as of October 30, 2026, with prices from £1,357 to £3,737, a £2,380 spread on the same certified stone. NZ Jewellers lists it at £3,737. 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.
