About this 3.56ct lab-grown radiant diamond

This 3.56ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG670483816 or 670483816. Listed at 10 retailers as of October 29, 2026, with prices from $1,313 to $5,713, a $4,400 spread on the same certified stone. Brilliant Earth lists it at $5,713. 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.
