About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561525671. Listed at 4 retailers as of October 31, 2026, with prices from HK$12,091 to HK$14,351, a HK$2,260 spread on the same certified stone. Blue Nile lists it at HK$14,351. 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.
