About this 1.59ct natural heart diamond

This 1.59ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 781623358. Listed at 5 retailers as of November 4, 2026, with prices from HK$32,165 to HK$67,731, a HK$35,566 spread on the same certified stone. MOH London lists it at HK$67,731. 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.
