Vintage Egyptian Revival Collar Necklace Bracelet & Earrings Alexis Kirk?

Very cool vintage two-tone leather and brass jewelry set. These pieces are unsigned thinking Alexis Kirk or knock-off. These have been with me for 20-25 years. I lost the hoop pieces for the earrings. It's an easy fix can buy at a craft/jewelry store. Measurements are approximate. Please see photos on measuring tape. Happy to answer questions.
