About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5553449493. Listed at 8 retailers as of October 30, 2026, with prices from €6,917 to €13,267, a €6,350 spread on the same certified stone. NZ Jewellers lists it at €13,267. 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.
