About this 0.91ct natural marquise diamond

This 0.91ct natural marquise sits in the just-under-one-carat band, graded E colour (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 1503835781. Listed at 2 retailers as of October 30, 2026, with prices from HK$50,940 to HK$80,418, a HK$29,478 spread on the same certified stone. Diamond Quarter lists it at HK$80,418. 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.
