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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2337639848. Listed at 13 retailers as of November 1, 2026, with prices from HK$4,449 to HK$6,599, a HK$2,150 spread on the same certified stone. Yorxs lists it at HK$6,599. 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.
