Listed at 4 retailers as of October 28, 2026, with prices from £3,674 to £5,279, a £1,605 spread on the same certified stone. Zales lists it at £5,279. 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.
