This 3.03ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG851692429 or 851692429. Listed at 8 retailers as of November 6, 2026, with prices from HK$3,127 to HK$19,907, a HK$16,780 spread on the same certified stone. Brilliant Earth lists it at HK$19,907. 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.
