The two main devices (symbols) in the Cranstoun blazon are the crane and bordure invecked. The two main tinctures (colors) are gules and argent.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 2. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.3.
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 4. In a sketch or drawing it is represented by plain, unmarked paper 5.
Birds of great variety occur throughout heraldry, at least in name 6. In truth, despite the proliferation of species, the actual depictions can sometimes be hard to distinguish! The crane, heron and stork are commonly to be found on a coat of arms but all tend to share the same stylised appearance 7. Guillim reckons the stork to the “emblem of filial duty” and also the “symbol of a grateful man”. 8
The border, (sometimes bordure) is a band running around the edge of the shield, following the edge contours and being differently coloured, possibly holding a series of small charges placed on top of it 9. To distinguish it from similar arms, heraldic artists developed a series of decorative edges (obviously these are applied only to the inner edge). Invected is a very pleasing decorative pattern, the exact opposite of the decoration known as engrailed. It consists of a series of small arcs joined side by side, with points inwards, (i.e. a series of outward “bulges”). Wade suggests that these closely related decorative edges can be taken to signify “earth or land” 10.
