This 4.26ct 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 LG787622969 or 787622969. Listed at 13 retailers as of October 30, 2026, with prices from HK$37,636 to HK$210,524, a HK$172,888 spread on the same certified stone. With Clarity lists it at HK$210,524. 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.
