Listed at 21 retailers as of October 29, 2026, with prices from $784 to $3,414, a $2,630 spread on the same certified stone. MOH London lists it at $3,414. 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.
