Blazon: Per pale argent a cross of Santiago gules between two escallops in base proper and azure a castle triple-towered argent windowed sable
I’ve chosen to blazon the escallops as proper, because while proper charges can be placed upon any metal, tincture, or fur, argent-on-argent is definitely not allowable. The “proper” color of a scallop shell is very similar to argent, so while this configuration is acceptable under the rules of blazon, it is probably not the most effective design choice.
