About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551370755. Listed at 8 retailers as of November 6, 2026, with prices from €1,807 to €2,964, a €1,156 spread on the same certified stone. Wholesale Diamonds Direct lists it at €2,964. 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.
