Listed at 11 retailers as of October 28, 2026, with prices from £737 to £5,842, a £5,105 spread on the same certified stone. Brilliant Earth lists it at £5,842. 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.
