Listed at 17 retailers as of November 5, 2026, with prices from £162 to £841, a £679 spread on the same certified stone. MOH London lists it at £841. 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.
