About this 3.31ct natural marquise diamond

This 3.31ct natural marquise sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 260000218806. Listed at 11 retailers as of November 1, 2026, with prices from £16,930 to £28,337, a £11,407 spread on the same certified stone. MOH London lists it at £28,337. 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.
