Listed at 4 retailers as of November 1, 2026, with prices from £1,662 to £3,476, a £1,813 spread on the same certified stone. NZ Jewellers lists it at £3,476. 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.
