This 1.18ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799643969 or 799643969. Listed at 8 retailers as of November 1, 2026, with prices from $557 to $4,443, a $3,887 spread on the same certified stone. Rare Carat lists it at $4,443. 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.
