Listed at 12 retailers as of October 25, 2026, with prices from $270 to $1,401, a $1,131 spread on the same certified stone. MOH London lists it at $1,401. 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.
