About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551949238. Listed at 6 retailers as of November 5, 2026, with prices from HK$28,975 to HK$37,886, a HK$8,911 spread on the same certified stone. Blue Nile lists it at HK$37,886. 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.
