About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1548559966. Listed at 14 retailers as of November 5, 2026, with prices from €1,581 to €4,040, a €2,458 spread on the same certified stone. NZ Jewellers lists it at €4,040. 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.
