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 HK$3,138 to HK$9,854, a HK$6,716 spread on the same certified stone. MOH London lists it at HK$9,854. 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.
