This 1.71ct 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), with a standard cut grade and certified by IGI LG712535601 or 712535601. Listed at 23 retailers as of October 30, 2026, with prices from HK$4,880 to HK$27,381, a HK$22,501 spread on the same certified stone. Brilliant Earth lists it at HK$27,381. 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.
