Listed at 6 retailers as of November 1, 2026, with prices from $1,271 to $3,104, a $1,833 spread on the same certified stone. MOH London lists it at $3,104. 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.
