VTG mother of pearl abalone abstract earrings

Vintage inlay earrings in a curved triangle abstract motif with mother of pearl, abalone, and what I believe to be onyx. Guessing from the 80s or 90s based on the shape. Gorgeous shimmery colors of black, white, and purple-green. Approximately 1”x1”, see measurements in pic. Excellent condition, although the earring backs do not match. **Can’t ship until mid-January! Please reach out with any questions or comments :)
