About this 0.5ct natural emerald diamond

This 0.5ct natural emerald sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6402378452. Listed at 4 retailers as of October 28, 2026, with prices from HK$3,570 to HK$7,961, a HK$4,391 spread on the same certified stone. MOH London lists it at HK$7,961. 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.
