About this 1.54ct lab-grown heart diamond

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 LG840618198 or 840618198. Listed at 3 retailers as of November 4, 2026, with prices from HK$7,712 to HK$26,732, a HK$19,020 spread on the same certified stone. Taylor and Hart lists it at HK$26,732. 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.
