Necklace :; colon/semicolon

This beautiful key belongs to a 1920 Underwood. Is probably one of the oldest pieces that I have in my collection and very rare to find. Its gold color shows the passing of time and the beauty of antique objects. These are very special symbols. Semicolons should introduce evidence or a reason for the preceding statement. A colon, on the other hand, should be used for a stronger, more direct relationship. It should provide emphasis, an example, or an explanation. What does this unique key mean to you?
