Listed at 8 retailers as of November 1, 2026, with prices from £542 to £1,394, a £852 spread on the same certified stone. MOH London lists it at £1,394. 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.
