Listed at 29 retailers as of October 30, 2026, with prices from £2,402 to £10,869, a £8,467 spread on the same certified stone. With Clarity lists it at £10,869. 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.
