What is The Typical Man-Gagement Ring? 
In recent times its very universal, with not really a look at me wow! Type approach.
It’s more of a Bold Masculine appeal that tends to be not drawing to much attention.
Generally not matching the females ring, featuring a single diamond inserted in the middle.
Men are going with more tougher metals as well, like tungsten& titanium. Gold still always in demand because the value will always be higher. Also you will see alot of custom designs as well with both mixing cross patterns as well as two-tone styles.
