I found my first ring ever today,and was second time out with T2.It is a Avon sterling silver black onyx.I found it where 2 houses were torn down last weeek and hauled away.The houses were probably built in 40's or 50's.It is hard to detect there because of all the small debris from that.I am going to go back there as much as I can before they build the dorms for college students.
