Listed at 15 retailers as of October 28, 2026, with prices from $182 to $1,435, a $1,253 spread on the same certified stone. Queensmith lists it at $1,435. 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.
