About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6455988523. Listed at 12 retailers as of November 1, 2026, with prices from HK$12,295 to HK$31,055, a HK$18,760 spread on the same certified stone. Moon Ocean lists it at HK$31,055. 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.
