About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 830659866. Listed at 4 retailers as of October 29, 2026, with prices from HK$36,494 to HK$73,525, a HK$37,031 spread on the same certified stone. MOH London lists it at HK$73,525. 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.
