About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6431067710. Listed at 15 retailers as of November 4, 2026, with prices from HK$14,546 to HK$34,170, a HK$19,624 spread on the same certified stone. MOH London lists it at HK$34,170. 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.
