About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded I 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 2566003503. Listed at 3 retailers as of November 1, 2026, with prices from HK$4,002 to HK$4,925, a HK$923 spread on the same certified stone. 77 Diamonds lists it at HK$4,925. 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.
