About this 3.12ct lab-grown radiant diamond

This 3.12ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG573303676 or 573303676. Listed at 14 retailers as of October 29, 2026, with prices from $2,480 to $9,012, a $6,532 spread on the same certified stone. Taylor and Hart lists it at $9,012. 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.
