JoseAB Hi @jcgude, sorry for the late reply.
The earrings are already small and discrete imho. Each measures 10mm (~0.4") in diameter and sticks out 5mm (~0.2") from the ear.
Here's a photo of how one looks on my mom's ear.
Anyway thanks a lot for your purchase, and if you still would like them to be smaller, I can certainly make them, so just tell me which size would you want them to be.
