Listed at 8 retailers as of October 29, 2026, with prices from $529 to $1,994, a $1,465 spread on the same certified stone. MOH London lists it at $1,994. 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.
