About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557673649. Listed at 16 retailers as of November 5, 2026, with prices from €7,963 to €13,584, a €5,620 spread on the same certified stone. NZ Jewellers lists it at €13,584. 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.
