Listed at 6 retailers as of October 26, 2026, with prices from $402 to $1,066, a $664 spread on the same certified stone. MOH London lists it at $1,066. 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.
