About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6445653262. Listed at 13 retailers as of October 29, 2026, with prices from HK$36,247 to HK$81,509, a HK$45,262 spread on the same certified stone. NZ Jewellers lists it at HK$81,509. 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.
