This 1.51ct 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 LG825655952 or 825655952. Listed at 21 retailers as of November 4, 2026, with prices from HK$5,720 to HK$28,166, a HK$22,447 spread on the same certified stone. Brilliant Earth lists it at HK$28,166. 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.
