Listed at 18 retailers as of October 25, 2026, with prices from $601 to $3,328, a $2,727 spread on the same certified stone. Queensmith lists it at $3,328. 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.
