About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1499218609. Listed at 9 retailers as of October 30, 2026, with prices from HK$17,229 to HK$22,360, a HK$5,131 spread on the same certified stone. Jared lists it at HK$22,360. 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.
