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 LG407981439 or 407981439. Listed at 10 retailers as of November 4, 2026, with prices from HK$4,629 to HK$28,077, a HK$23,448 spread on the same certified stone. MOH London lists it at HK$28,077. 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.
