Family Crest Rings - Irish Coat of Arms jewelry - allcladdagh.com
"This is a special piece of Jewellery as it contains your Family Coat of Arms or Family Crest, hand engraved on a heavy 14kt signet ring. It is a ring that can be passed down from generation to generation and is available in shield or oval.
Shield: The colors and charges (lions, designs, etc. that appear on the shield) are a part of the official blazon, but the shape of the shield is not. Shield shapes vary according to the geographical origin as well as the time period.
Crest: Also a part of the official blazon, the crest is whatever appears above the helm. (Note that there is not always a crest for every coat of arms.) "
