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 26, 2026, with prices from $263 to $2,690, a $2,427 spread on the same certified stone. Brilliant Earth lists it at $2,690. 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.
