Listed at 16 retailers as of October 31, 2026, with prices from £1,477 to £7,262, a £5,785 spread on the same certified stone. Novita Diamonds lists it at £7,262. 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.
