Listed at 8 retailers as of October 28, 2026, with prices from $801 to $3,722, a $2,921 spread on the same certified stone. MOH London lists it at $3,722. 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.
