About this 1.51ct natural heart diamond

This 1.51ct 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 standard cut grade and certified by IGI 563214076. Listed at 15 retailers as of October 30, 2026, with prices from HK$27,630 to HK$66,543, a HK$38,913 spread on the same certified stone. NZ Jewellers lists it at HK$66,543. 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.
