About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557752766. Listed at 13 retailers as of October 31, 2026, with prices from €3,136 to €5,621, a €2,484 spread on the same certified stone. Helzberg Diamonds lists it at €5,621. 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.
