About this 1.39ct lab-grown cushion diamond

This 1.39ct 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 LG623488096 or 623488096. Listed at 3 retailers as of November 4, 2026, with prices from HK$11,141 to HK$23,694, a HK$12,553 spread on the same certified stone. Kay Jewelers lists it at HK$23,694. 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.
