About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7551943530. Listed at 18 retailers as of November 2, 2026, with prices from HK$2,213 to HK$6,876, a HK$4,662 spread on the same certified stone. MOH London lists it at HK$6,876. 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.
