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 6361749218. Listed at 17 retailers as of November 2, 2026, with prices from HK$16,741 to HK$37,953, a HK$21,212 spread on the same certified stone. MOH London lists it at HK$37,953. 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.
