About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6545678263. Listed at 15 retailers as of November 5, 2026, with prices from HK$24,272 to HK$54,830, a HK$30,558 spread on the same certified stone. NZ Jewellers lists it at HK$54,830. 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.
