Listed at 8 retailers as of October 28, 2026, with prices from £433 to £2,199, a £1,766 spread on the same certified stone. NZ Jewellers lists it at £2,199. 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.
