About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-carat band, graded F 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 6541073603. Listed at 8 retailers as of November 2, 2026, with prices from HK$3,937 to HK$6,975, a HK$3,038 spread on the same certified stone. MOH London lists it at HK$6,975. 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.
