Listed at 19 retailers as of October 31, 2026, with prices from £234 to £1,455, a £1,221 spread on the same certified stone. Brilliant Earth lists it at £1,455. 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.
