About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded G 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 3555909668. Listed at 15 retailers as of November 4, 2026, with prices from €2,435 to €4,631, a €2,196 spread on the same certified stone. Helzberg Diamonds lists it at €4,631. 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.
