About this 1.57ct natural heart diamond

This 1.57ct natural heart sits in the one-and-a-half to two carat band, graded H 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 2546192780. Listed at 8 retailers as of October 31, 2026, with prices from HK$39,681 to HK$73,711, a HK$34,030 spread on the same certified stone. NZ Jewellers lists it at HK$73,711. 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.
