About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2558612489. Listed at 11 retailers as of November 5, 2026, with prices from €2,116 to €3,646, a €1,529 spread on the same certified stone. Wholesale Diamonds Direct lists it at €3,646. 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.
