About this 1.26ct lab-grown cushion diamond

This 1.26ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634337 or 840634337. Listed at 7 retailers as of October 29, 2026, with prices from HK$3,507 to HK$20,871, a HK$17,364 spread on the same certified stone. Brilliant Earth lists it at HK$20,871. 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.
