This 1.01ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407972863 or 407972863. Listed at 11 retailers as of November 3, 2026, with prices from HK$4,629 to HK$28,157, a HK$23,528 spread on the same certified stone. MOH London lists it at HK$28,157. 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.
