About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7235137535. Listed at 12 retailers as of October 30, 2026, with prices from HK$33,784 to HK$74,409, a HK$40,625 spread on the same certified stone. NZ Jewellers lists it at HK$74,409. 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.
