Listed at 8 retailers as of November 4, 2026, with prices from $470 to $1,275, a $805 spread on the same certified stone. MOH London lists it at $1,275. 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.
