About this 0.3ct natural marquise diamond

This 0.3ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551661709. Listed at 10 retailers as of October 31, 2026, with prices from HK$2,912 to HK$8,321, a HK$5,408 spread on the same certified stone. 18carati lists it at HK$8,321. 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.
