This 6.12ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754595528 or 754595528. Listed at 18 retailers as of October 27, 2026, with prices from HK$128,238 to HK$422,538, a HK$294,300 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$422,538. 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.
