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 LG818654467 or 818654467. Listed at 13 retailers as of November 4, 2026, with prices from HK$4,425 to HK$39,307, a HK$34,882 spread on the same certified stone. Do Amore Diamonds lists it at HK$39,307.
