Listed at 16 retailers as of October 30, 2026, with prices from £653 to £2,672, a £2,019 spread on the same certified stone. Brilliant Earth lists it at £2,672. 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.
