About this 0.3ct natural marquise diamond

This 0.3ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1557603073. Listed at 4 retailers as of November 1, 2026, with prices from HK$2,126 to HK$2,819, a HK$693 spread on the same certified stone. 77 Diamonds lists it at HK$2,819. 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.
