Circle K Ireland

2008-2018
Topaz Energy was founded in 2005 by Ion Equity to acquire the Irish filling station and home heating operation of Royal Dutch Shell plc, Irish Shell Limited, as well as the Irish operations of Statoil. The first Topaz-branded stations opened in Dublin in 2008 and the brand replaced Shell and Statoil stations across Ireland during 2008-09.

2018-present
In December 2015, it was announced that Topaz would be sold to Alimentation Couche-Tard, with the deal closing in spring 2016. In 2018, the Topaz brand name began being phased out and replaced with Couche-Tard's international brand Circle K, starting in May.
