This 4.28ct 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 LG804665090 or 804665090. Listed at 10 retailers as of October 30, 2026, with prices from HK$32,003 to HK$202,576, a HK$170,573 spread on the same certified stone. Do Amore Diamonds lists it at HK$202,576. 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.
