This chainmaille necklace is made from a pattern called Full Persian and is attached to flower pendant that is a genuine Swarovski Element. The chain is about 20 inches long, but can be lengthened or shortened if desired. The chain itself is made from 20 gauge aluminum rings that are hand rolled and cut. The aluminum makes it very light-weight, but the pattern of chainmaille ensures that it is very strong. The connection points are the weakest parts of the chain and care should be taken to prevent too much pulling on those areas, but otherwise the necklace should stand up to everyday wear and tear.
