About this 3.91ct lab-grown radiant diamond

This 3.91ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG708563402 or 708563402. Listed at 17 retailers as of October 29, 2026, with prices from $1,432 to $15,170, a $13,738 spread on the same certified stone. Brilliant Earth lists it at $15,170. 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.
