Listed at 19 retailers as of October 29, 2026, with prices from $1,445 to $6,543, a $5,098 spread on the same certified stone. Riddles Jewelry lists it at $6,543. 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.
