Occurrence in Wales: hematite is widespread in Wales, but notable occurrences are few. Most records detail hematite as inclusions within other minerals or rocks, giving them a characterisitic red colour. Localities noted for good crystallized specimens include the iron mines of South Wales and Penrhyn Slate Quarry, near Bethesda in North Wales.
