Don't get higher that 14K gold for a chain and cross you plan to wear all the time as it will be softer and can break more easily. I'm orthodox but for some reason I got a catholic cross with Jesus on it when I was young and didn't know the difference but I like it more than the plain orthodox crosses. I feel His presence more closely I guess. Here in Romania people usually wear them under their shirt as it's not a fashion thing to flaunt. Also gipsy might attack you to steal it 🤣
