About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2567665932. Listed at 3 retailers as of November 2, 2026, with prices from HK$1,337 to HK$4,255, a HK$2,918 spread on the same certified stone. 77 Diamonds lists it at HK$4,255. 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.
