About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2235825304. Listed at 6 retailers as of November 2, 2026, with prices from HK$157,055 to HK$209,643, a HK$52,587 spread on the same certified stone. Yorxs lists it at HK$209,643. 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.
