This 1.4ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768632638 or 768632638. Listed at 13 retailers as of November 4, 2026, with prices from HK$2,762 to HK$20,399, a HK$17,637 spread on the same certified stone. Do Amore Diamonds lists it at HK$20,399. 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.
