This 0.51ct lab-grown princess sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG836609873 or 836609873. Listed at 9 retailers as of October 29, 2026, with prices from HK$2,730 to HK$7,632, a HK$4,902 spread on the same certified stone. MOH London lists it at HK$7,632. 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.
