About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1242079760. Listed at 3 retailers as of November 2, 2026, with prices from HK$11,431 to HK$18,315, a HK$6,884 spread on the same certified stone. MOH London lists it at HK$18,315. 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.
