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 LG833668461 or 833668461. Listed at 16 retailers as of November 1, 2026, with prices from $539 to $2,706, a $2,167 spread on the same certified stone. Reve Diamonds lists it at $2,706. 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.
