About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded I 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 6565217403. Listed at 10 retailers as of October 31, 2026, with prices from HK$5,295 to HK$9,462, a HK$4,167 spread on the same certified stone. Frank Darling lists it at HK$9,462. 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.
