Listed at 16 retailers as of October 27, 2026, with prices from £546 to £2,540, a £1,995 spread on the same certified stone. Queensmith lists it at £2,540. 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.
