Listed at 9 retailers as of October 27, 2026, with prices from $620 to $3,839, a $3,219 spread on the same certified stone. MOH London lists it at $3,839. 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.
