About this 0.8ct natural heart diamond

This 0.8ct natural heart sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6401859743. Listed at 18 retailers as of November 1, 2026, with prices from HK$15,488 to HK$33,162, a HK$17,674 spread on the same certified stone. MOH London lists it at HK$33,162. 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.
