This 1.41ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG783648803 or 783648803. Listed at 9 retailers as of October 29, 2026, with prices from $368 to $4,170, a $3,802 spread on the same certified stone. Brilliant Earth lists it at $4,170. 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.
