Listed at 16 retailers as of November 1, 2026, with prices from £194 to £1,034, a £839 spread on the same certified stone. Reve Diamonds lists it at £1,034. 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.
