About this 1.27ct lab-grown cushion diamond

This 1.27ct 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 standard cut grade and certified by IGI LG831694098 or 831694098. Listed at 13 retailers as of October 26, 2026, with prices from HK$4,331 to HK$20,048, a HK$15,717 spread on the same certified stone. MOH London lists it at HK$20,048. 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.
