Vintage Mother Pearl Silver Buckle with Abalone Center Stone

Vintage RARE ladies belt buckle with Mother of Pearl & silver inlay. Abalone round gemstone set in center. Back is stamped with Oval Mfg Co. and ‘Frente de playa’ which translates to silver front. I researched this buckle for HOURS and could not find anything about Oval Manufacturing Company. It is a beautiful piece and is very well crafted. I cleaned the front with a polishing cloth but left the decision to do any deep cleaning up to its new owner. Please refer to photos for further description. I will consider any reasonable offer!! Thank you 😊
