Listed at 21 retailers as of October 30, 2026, with prices from £343 to £3,179, a £2,836 spread on the same certified stone. Brilliant Earth lists it at £3,179. 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.
