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 D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634410 or 840634410. Listed at 13 retailers as of November 1, 2026, with prices from HK$3,695 to HK$18,877, a HK$15,181 spread on the same certified stone. Helzberg Diamonds lists it at HK$18,877. 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.
