About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6545538499. Listed at 14 retailers as of November 1, 2026, with prices from HK$69,014 to HK$122,225, a HK$53,211 spread on the same certified stone. MOH London lists it at HK$122,225. 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.
