This detailed Clan Crest signet ring displays the MacThomas crest of a mountain cat, with a serpent’s head grasped in his right paw, and the tail entwined in his left paw. The proud MacThomas clan motto is DEO JUVANTE INVIDIAM SUPERABO, meaning "I will overcome envy with God’s help". The smooth wide band gently tapers from the face towards the back. The family names Thompson and Thomson are significant septs of this clan.
