About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded H 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 6541584869. Listed at 15 retailers as of November 1, 2026, with prices from HK$6,729 to HK$16,282, a HK$9,553 spread on the same certified stone. MOH London lists it at HK$16,282. 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.
