About this 3.16ct lab-grown radiant diamond

This 3.16ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821655501 or 821655501. Listed at 7 retailers as of October 28, 2026, with prices from $2,140 to $5,001, a $2,861 spread on the same certified stone. With Clarity lists it at $5,001. 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.
