About this 0.91ct lab-grown heart diamond

This 0.91ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG720557271 or 720557271. Listed at 18 retailers as of October 26, 2026, with prices from HK$2,134 to HK$14,201, a HK$12,067 spread on the same certified stone. Brilliant Earth lists it at HK$14,201. 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.
