About this 6.5ct lab-grown cushion diamond

This 6.5ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG776688550 or 776688550. Listed at 18 retailers as of October 30, 2026, with prices from HK$11,941 to HK$64,256, a HK$52,315 spread on the same certified stone. Brilliant Earth lists it at HK$64,256. 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.
