About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded G 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 6512617243. Listed at 3 retailers as of October 31, 2026, with prices from HK$1,987 to HK$4,868, a HK$2,881 spread on the same certified stone. 77 Diamonds lists it at HK$4,868. 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.
