This 1.6ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768631244 or 768631244. Listed at 15 retailers as of October 26, 2026, with prices from HK$4,001 to HK$28,951, a HK$24,949 spread on the same certified stone. Brilliant Earth lists it at HK$28,951. 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.
