This 3.12ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG573303676 or 573303676. Listed at 14 retailers as of October 31, 2026, with prices from HK$15,221 to HK$55,308, a HK$40,087 spread on the same certified stone. Taylor and Hart lists it at HK$55,308. 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.
