This 3ct lab-grown princess sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG512231591 or 512231591. Listed at 15 retailers as of November 4, 2026, with prices from HK$4,362 to HK$30,832, a HK$26,470 spread on the same certified stone. Brilliant Earth lists it at HK$30,832. 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.
