This 1.54ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831604179 or 831604179. Listed at 21 retailers as of November 4, 2026, with prices from HK$5,853 to HK$34,757, a HK$28,904 spread on the same certified stone. Brilliant Earth lists it at HK$34,757. 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.
