About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded I 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 7556591696. Listed at 20 retailers as of November 1, 2026, with prices from HK$2,096 to HK$7,025, a HK$4,929 spread on the same certified stone. MOH London lists it at HK$7,025. 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.
