About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded I 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 6465552253. Listed at 4 retailers as of October 28, 2026, with prices from HK$3,295 to HK$7,284, a HK$3,989 spread on the same certified stone. MOH London lists it at HK$7,284. 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.
