ATI MEXICO?? Abalone Shell Inlay Long Oval Pendant 925 Sterling Silver

This pendant belonged to my Mother-in-Law. The back is stamped "Mexico 925". While looking this pendant up on the internet and trying to get more information on it, I believe the brand is ATI Mexico. -925 Sterling Silver -Beautiful Abalone Shell Inlay -Pendant Only - does not come with a chain. In beautiful condition. It does need a good polishing and there are some surface scratches on the back. Please see pictures for details and measurements.
