About this 3.1ct lab-grown radiant diamond

This 3.1ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG844669209 or 844669209. Listed at 18 retailers as of October 27, 2026, with prices from $1,666 to $6,781, a $5,115 spread on the same certified stone. Taylor and Hart lists it at $6,781. 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.
