About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557721312. Listed at 13 retailers as of November 4, 2026, with prices from €356 to €1,119, a €763 spread on the same certified stone. MOH London lists it at €1,119. 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.
