This 1.22ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG578341098 or 578341098. Listed at 20 retailers as of October 29, 2026, with prices from $831 to $4,017, a $3,186 spread on the same certified stone. MOH London lists it at $4,017. 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.
