Listed at 26 retailers as of October 28, 2026, with prices from $8,095 to $15,287, a $7,192 spread on the same certified stone. MOH London lists it at $15,287. 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.
