About this 0.5ct natural emerald diamond

This 0.5ct natural emerald sits in the half to three-quarter 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 1518721524. Listed at 18 retailers as of October 27, 2026, with prices from HK$3,175 to HK$13,433, a HK$10,258 spread on the same certified stone. NZ Jewellers lists it at HK$13,433. 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.
