This 6.12ct lab-grown radiant sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG643452024 or 643452024. Listed at 26 retailers as of November 2, 2026, with prices from $1,090 to $5,410, a $4,320 spread on the same certified stone. Brilliant Earth lists it at $5,410. 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.
