Listed at 7 retailers as of October 30, 2026, with prices from £262 to £1,379, a £1,117 spread on the same certified stone. Aurelinne lists it at £1,379. 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.
