About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded J 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 5221061761. Listed at 19 retailers as of November 1, 2026, with prices from HK$13,088 to HK$29,283, a HK$16,195 spread on the same certified stone. MOH London lists it at HK$29,283. 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.
