About this 0.84ct lab-grown cushion diamond

This 0.84ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616809 or 778616809. Listed at 10 retailers as of October 30, 2026, with prices from HK$3,821 to HK$24,025, a HK$20,203 spread on the same certified stone. MOH London lists it at HK$24,025. 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.
