About this 1.22ct lab-grown cushion diamond

This 1.22ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG730503401 or 730503401. Listed at 14 retailers as of October 30, 2026, with prices from HK$2,001 to HK$10,062, a HK$8,061 spread on the same certified stone. Reve Diamonds lists it at HK$10,062. 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.
