About this 4.05ct natural marquise diamond

This 4.05ct natural marquise sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 10665904. Listed at 7 retailers as of October 29, 2026, with prices from €38,828 to €64,474, a €25,646 spread on the same certified stone. MOH London lists it at €64,474. 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.
