This 6.09ct lab-grown radiant sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG750521141 or 750521141. Listed at 14 retailers as of October 29, 2026, with prices from $2,144 to $11,442, a $9,298 spread on the same certified stone. Brilliant Earth lists it at $11,442. 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.
