This 0.55ct 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 LG825666407 or 825666407. Listed at 17 retailers as of November 1, 2026, with prices from $360 to $1,823, a $1,463 spread on the same certified stone. Reve Diamonds lists it at $1,823. 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.
