This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG844647089 or 844647089. Listed at 15 retailers as of October 24, 2026, with prices from HK$832 to HK$6,526, a HK$5,695 spread on the same certified stone. MOH London lists it at HK$6,526. 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.
