About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231702396. Listed at 6 retailers as of November 1, 2026, with prices from HK$17,846 to HK$37,314, a HK$19,468 spread on the same certified stone. NZ Jewellers lists it at HK$37,314. 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.
