This 1ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845697289 or 845697289. Listed at 17 retailers as of October 30, 2026, with prices from HK$1,875 to HK$10,331, a HK$8,456 spread on the same certified stone. Reve Diamonds lists it at HK$10,331. 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.
