About this 0.8ct natural heart diamond

This 0.8ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 566320172. Listed at 7 retailers as of November 1, 2026, with prices from HK$8,395 to HK$16,053, a HK$7,658 spread on the same certified stone. MOH London lists it at HK$16,053. 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.
