About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6505477862. Listed at 2 retailers as of October 30, 2026, with prices from HK$5,719 to HK$11,169, a HK$5,450 spread on the same certified stone. Diamond Quarter lists it at HK$11,169. 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.
