Listed at 22 retailers as of November 1, 2026, with prices from £472 to £5,045, a £4,573 spread on the same certified stone. Brilliant Earth lists it at £5,045. 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.
