This 1.63ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG613350559 or 613350559. Listed at 17 retailers as of October 29, 2026, with prices from HK$3,135 to HK$15,614, a HK$12,479 spread on the same certified stone. Brilliant Earth lists it at HK$15,614. 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.
