About this 3.07ct lab-grown cushion diamond

This 3.07ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG780662858 or 780662858. Listed at 13 retailers as of October 31, 2026, with prices from HK$18,273 to HK$75,083, a HK$56,811 spread on the same certified stone. Brilliant Earth lists it at HK$75,083. 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.
