This 0.54ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825666410 or 825666410. Listed at 16 retailers as of October 30, 2026, with prices from $354 to $1,807, a $1,452 spread on the same certified stone. Reve Diamonds lists it at $1,807. 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.
