This 1.54ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG654473132 or 654473132. Listed at 11 retailers as of November 4, 2026, with prices from HK$3,797 to HK$34,835, a HK$31,038 spread on the same certified stone. Brilliant Earth lists it at HK$34,835. 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.
