About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556439722. Listed at 14 retailers as of November 1, 2026, with prices from €2,630 to €5,069, a €2,438 spread on the same certified stone. NZ Jewellers lists it at €5,069. 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.
