About this 1.34ct lab-grown heart diamond

This 1.34ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG839698473 or 839698473. Listed at 12 retailers as of November 2, 2026, with prices from HK$2,511 to HK$19,379, a HK$16,868 spread on the same certified stone. Brilliant Earth lists it at HK$19,379. 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.
