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 7551345171. Listed at 20 retailers as of October 30, 2026, with prices from HK$8,431 to HK$27,626, a HK$19,195 spread on the same certified stone. NZ Jewellers lists it at HK$27,626. 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.
