Vintage Mother of Pearl Clutch Square Pattern

This is lovely, a beautiful cream and off-white and iridescent/opalescent vintage clutch made up of tiny square mother of pearl sections and sewn together. I don’t know the brand or the year. I also have no idea if this is genuine or lab created mother of pearl. Please note that I am working on closing my shop even though I just posted this, I have some major life changes coming up and will need to temporarily or permanently stop my part-time business. I am open to offers, and bundles are encouraged!
