The Shield of Arms of The Buchanan Society is in gold, bearing a black Scottish Lion Rampant, an open book (signifying learning) and a purse (signifying money). The crest includes a Ducal Cap of Maintenance held in the right fist and surmounted by a rose. The foliage on the crest comprises Bilberry and Oak, both of which flourish on Clairinch, the island in Loch Lomond which belongs to the Buchanan Society.
