Listed at 16 retailers as of November 4, 2026, with prices from $655 to $3,161, a $2,506 spread on the same certified stone. MOH London lists it at $3,161. 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.
