Listed at 21 retailers as of October 30, 2026, with prices from £1,318 to £5,360, a £4,042 spread on the same certified stone. Taylor and Hart lists it at £5,360. 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.
