About this 1.09ct lab-grown princess diamond

This 1.09ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG720502721 or 720502721. Listed at 13 retailers as of October 29, 2026, with prices from HK$2,385 to HK$19,379, a HK$16,994 spread on the same certified stone. Do Amore Diamonds lists it at HK$19,379. 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.
