This 3.04ct 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 LG827604371 or 827604371. Listed at 8 retailers as of November 4, 2026, with prices from HK$5,259 to HK$19,985, a HK$14,726 spread on the same certified stone. Brilliant Earth lists it at HK$19,985. 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.
