Listed at 16 retailers as of November 4, 2026, with prices from £489 to £2,002, a £1,513 spread on the same certified stone. NZ Jewellers lists it at £2,002. 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.
