This 3.03ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG546215433 or 546215433. Listed at 15 retailers as of November 6, 2026, with prices from HK$3,911 to HK$21,161, a HK$17,250 spread on the same certified stone. Brilliant Earth lists it at HK$21,161. 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.
