About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561381740. Listed at 16 retailers as of November 2, 2026, with prices from €289 to €891, a €602 spread on the same certified stone. MOH London lists it at €891. 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.
