About this 1.21ct lab-grown princess diamond

This 1.21ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG618403171 or 618403171. Listed at 3 retailers as of October 28, 2026, with prices from HK$5,955 to HK$27,852, a HK$21,897 spread on the same certified stone. Do Amore Diamonds lists it at HK$27,852. 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.
