About this 1.45ct lab-grown heart diamond

This 1.45ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831698098 or 831698098. Listed at 11 retailers as of November 4, 2026, with prices from HK$3,774 to HK$24,008, a HK$20,234 spread on the same certified stone. Brilliant Earth lists it at HK$24,008. 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.
