This substantial Victorian cannetille Aquamarine and seed pearl necklace was converted from a large piece, I am not sure what it was. I feel like it could have come from a larger collar necklace and was broken apart. The Aquamarine is a striking deep color with a sea foam green hue. The 14k yellow gold chain is permanent and strung through the hidden bail.

Aquamarine: shows indication of no heat treatment due to noticeable green hue that is eliminated from heat treatment.
