This 1.01ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG772657853 or 772657853. Listed at 23 retailers as of November 4, 2026, with prices from HK$1,859 to HK$16,555, a HK$14,695 spread on the same certified stone. Brilliant Earth lists it at HK$16,555. 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.
