About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551594637. Listed at 18 retailers as of October 30, 2026, with prices from HK$18,298 to HK$41,865, a HK$23,567 spread on the same certified stone. NZ Jewellers lists it at HK$41,865. 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.
