About this 1.03ct lab-grown heart diamond

This 1.03ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825667231 or 825667231. Listed at 18 retailers as of November 2, 2026, with prices from HK$3,295 to HK$21,263, a HK$17,968 spread on the same certified stone. Brilliant Earth lists it at HK$21,263. 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.
