About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded J 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 1453449582. Listed at 11 retailers as of October 30, 2026, with prices from HK$2,503 to HK$5,510, a HK$3,007 spread on the same certified stone. 77 Diamonds lists it at HK$5,510. 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.
