About this 0.41ct natural marquise diamond

This 0.41ct natural marquise sits in the sub-half-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 GIA 1236370409. Listed at 5 retailers as of November 1, 2026, with prices from $478 to $822, a $344 spread on the same certified stone. MOH London lists it at $822. 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.
