The item is a Saint Matthew silver pendant that measures 24 millimeters round or just under a inch. The back is plain and can be engraved at no charge by us. The pendant will come with a 24 inch long silver curb chain. The chain will have no catch. You can just slide it over your head. If you want a 18 inch chain the price would be 118.50 for this item. I can add any style or length chain you would like. Saint Matthew is the patron saint of accountants and bankers. I will provide a nice pendant box. This item has to be made and put together so please allow about 5 days before I can ship it.
