About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557391749. Listed at 8 retailers as of November 5, 2026, with prices from HK$19,613 to HK$25,742, a HK$6,129 spread on the same certified stone. GemTrove lists it at HK$25,742. 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.
