About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3515479566. Listed at 12 retailers as of October 30, 2026, with prices from HK$41,213 to HK$79,030, a HK$37,816 spread on the same certified stone. NZ Jewellers lists it at HK$79,030. 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.
