Listed at 11 retailers as of October 31, 2026, with prices from $1,087 to $5,569, a $4,482 spread on the same certified stone. MOH London lists it at $5,569. 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.
