==Geology== The Brookeborough Diamond, the only gem-quality diamond to have been found in Ireland, was discovered in the Colebrooke River in 1816. Karelian Diamond Resources plc, a Dublin-based company, was awarded a prospecting licence in the area in 2019 and undertook a sampling program which found chromite in stream sediments from the river.<ref>{{cite news|url=https://fermanaghherald.com/2021/11/diamond-mine-company-excited-by-fermanagh-tests/|title=Diamond mine company 'excited' by Fermanagh tests|newspaper=Fermanagh Herald|date=26 November 2021|accessdate=21 July 2022|first=Roisin|last=Henderson}}</ref>
