About this 1.23ct lab-grown princess diamond

This 1.23ct lab-grown princess sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605341016 or 605341016. Listed at 9 retailers as of November 4, 2026, with prices from HK$1,655 to HK$8,090, a HK$6,435 spread on the same certified stone. MOH London lists it at HK$8,090. 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.
