About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded G 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 7551480888. Listed at 14 retailers as of November 1, 2026, with prices from HK$8,128 to HK$28,562, a HK$20,434 spread on the same certified stone. Moon Ocean lists it at HK$28,562. 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.
