About this 1.34ct lab-grown cushion diamond

This 1.34ct 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), with a very-good cut grade and certified by IGI LG747513181 or 747513181. Listed at 17 retailers as of November 4, 2026, with prices from HK$4,480 to HK$27,539, a HK$23,059 spread on the same certified stone. Brilliant Earth lists it at HK$27,539. 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.
