About this 6.42ct natural marquise diamond

This 6.42ct natural marquise sits in the over five 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 HRD 260000254990. Listed at 4 retailers as of November 1, 2026, with prices from €67,969 to €123,286, a €55,317 spread on the same certified stone. MOH London lists it at €123,286. 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.
