Listed at 10 retailers as of November 4, 2026, with prices from £2,836 to £5,120, a £2,284 spread on the same certified stone. MOH London lists it at £5,120. 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.
