Listed at 5 retailers as of November 4, 2026, with prices from £964 to £2,986, a £2,022 spread on the same certified stone. Taylor and Hart lists it at £2,986. 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.
