About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG768628612 or 768628612. Listed at 13 retailers as of October 30, 2026, with prices from HK$17,182 to HK$77,319, a HK$60,137 spread on the same certified stone. Blue Nile lists it at HK$77,319. 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.
