Quite the comprehensive post.
Welcome to our #ladiesofhive community
I'm rather fond of gold and silver myself.
May I recommend that you properly attribute/credit your photo sources used in this post unless they are your photos. It saves you/us copyright issues later on. 😀
Thank you, and welcome to Hive, our Social Block Chain.
