About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG838632987 or 838632987. Listed at 15 retailers as of October 29, 2026, with prices from HK$4,150 to HK$16,351, a HK$12,201 spread on the same certified stone. MOH London lists it at HK$16,351. 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.
