This 15.09ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG776692857 or 776692857. Listed at 16 retailers as of November 1, 2026, with prices from HK$31,836 to HK$136,428, a HK$104,592 spread on the same certified stone. With Clarity lists it at HK$136,428. 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.
