About this 1.22ct lab-grown oval diamond

This 1.22ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG770640663 or 770640663. Listed at 25 retailers as of October 29, 2026, with prices from HK$2,063 to HK$16,790, a HK$14,726 spread on the same certified stone. Brilliant Earth lists it at HK$16,790. 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.
