About this 0.54ct natural marquise diamond

This 0.54ct natural marquise sits in the half to three-quarter carat band, graded I 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 2557963981. Listed at 15 retailers as of November 5, 2026, with prices from £290 to £1,328, a £1,038 spread on the same certified stone. NZ Jewellers lists it at £1,328. 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.
