Identify Your Wedding Band Maker: Finding Replacement Rings

Question
I am looking to replace a lost wedding band for my husband I cannot find the ring anywhere. I thought maybe I could find the maker and see where their rings are carried. On the inside of my ring is of course the 10k marking and then the stamp of a shape that looks like a graduation cap.  Can you help me?

It may be easier to describe the ring and I will tell you who other mfg. are that make this ring. Do you have a picture of the ring? wedding album? Mfg tend to make similar rings or the exact rings, nothing today is exclusive to one mfg. unless there is a trademark to patent on an exclusive design but even then rings are reproduced...
all the best
