About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J colour (near-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 3555701588. Listed at 3 retailers as of November 3, 2026, with prices from HK$36,209 to HK$43,263, a HK$7,054 spread on the same certified stone. Blue Nile lists it at HK$43,263. 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.
