Listed at 20 retailers as of November 2, 2026, with prices from £159 to £976, a £817 spread on the same certified stone. Brilliant Earth lists it at £976. 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.
