This 0.77ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658685 or 818658685. Listed at 17 retailers as of November 3, 2026, with prices from $434 to $1,950, a $1,516 spread on the same certified stone. Reve Diamonds lists it at $1,950. 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.
