About this 0.77ct natural marquise diamond

This 0.77ct natural marquise sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555866191. Listed at 9 retailers as of November 5, 2026, with prices from €364 to €841, a €477 spread on the same certified stone. Frank Darling lists it at €841. 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.
