About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J 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 2241098365. Listed at 15 retailers as of October 31, 2026, with prices from €3,045 to €5,456, a €2,411 spread on the same certified stone. Helzberg Diamonds lists it at €5,456. 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.
