Listed at 10 retailers as of October 31, 2026, with prices from £683 to £5,247, a £4,564 spread on the same certified stone. Brilliant Earth lists it at £5,247. 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.
