Listed at 17 retailers as of November 1, 2026, with prices from $277 to $1,377, a $1,100 spread on the same certified stone. MOH London lists it at $1,377. 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.
