Listed at 17 retailers as of October 26, 2026, with prices from £424 to £2,286, a £1,862 spread on the same certified stone. MOH London lists it at £2,286. 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.
