Listed at 8 retailers as of November 4, 2026, with prices from £2,453 to £4,610, a £2,156 spread on the same certified stone. With Clarity lists it at £4,610. 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.
