This 1.02ct 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 LG745520207 or 745520207. Listed at 26 retailers as of October 27, 2026, with prices from $163 to $1,870, a $1,707 spread on the same certified stone. Zales lists it at $1,870. 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.
