About this 0.9ct natural heart diamond

This 0.9ct natural heart 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 1415231999. Listed at 19 retailers as of November 1, 2026, with prices from HK$17,684 to HK$41,574, a HK$23,890 spread on the same certified stone. Moon Ocean lists it at HK$41,574. 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.
