This 1.16ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG683590375 or 683590375. Listed at 14 retailers as of October 28, 2026, with prices from $278 to $1,507, a $1,229 spread on the same certified stone. Reve Diamonds lists it at $1,507. 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.
