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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6471259389. Listed at 14 retailers as of November 4, 2026, with prices from HK$12,955 to HK$27,422, a HK$14,467 spread on the same certified stone. MOH London lists it at HK$27,422. 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.
