This 4.51ct lab-grown emerald sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG594330416 or 594330416. Listed at 17 retailers as of October 26, 2026, with prices from HK$4,456 to HK$24,033, a HK$19,577 spread on the same certified stone. MOH London lists it at HK$24,033. 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.
