About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1459682994. Listed at 6 retailers as of November 4, 2026, with prices from HK$16,513 to HK$31,941, a HK$15,427 spread on the same certified stone. MOH London lists it at HK$31,941. 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.
