About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552395259. Listed at 16 retailers as of November 5, 2026, with prices from HK$4,264 to HK$18,144, a HK$13,880 spread on the same certified stone. NZ Jewellers lists it at HK$18,144. 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.
