About this 1.37ct lab-grown cushion diamond

This 1.37ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831698113 or 831698113. Listed at 14 retailers as of October 31, 2026, with prices from HK$4,017 to HK$20,085, a HK$16,068 spread on the same certified stone. Brilliant Earth lists it at HK$20,085. 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.
