About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5212928897. Listed at 15 retailers as of October 28, 2026, with prices from HK$42,602 to HK$93,803, a HK$51,201 spread on the same certified stone. NZ Jewellers lists it at HK$93,803. 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.
