About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558632218. Listed at 12 retailers as of November 5, 2026, with prices from €5,449 to €8,946, a €3,497 spread on the same certified stone. Helzberg Diamonds lists it at €8,946. 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.
