Listed at 4 retailers as of November 1, 2026, with prices from $851 to $2,510, a $1,659 spread on the same certified stone. Rare Carat lists it at $2,510. 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.
