Listed at 6 retailers as of October 28, 2026, with prices from £971 to £1,122, a £151 spread on the same certified stone. Loose Grown Diamond lists it at £1,122. 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.
