About this 0.41ct natural marquise diamond

This 0.41ct natural marquise sits in the sub-half-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7552488329. Listed at 17 retailers as of November 2, 2026, with prices from €256 to €825, a €569 spread on the same certified stone. MOH London lists it at €825. 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.
