Diamond Phil's is a jewelry store (if you couldn't tell) in Morris Plains off Route 10. It's not a big shop which I think is a good thing in the Jewelry Business. Phil's is not based on quantity sales like chains. You'll get the personal attention you need.
In addition to the on display items, he's got plenty of catalogs and can make specialty items for you as well. Watch batteries can be replaced plus cleanings. It's full service.
He's been in business the better part of 15 years and has become a staple in the local community. I've bouthg plenty of items for myself and loved ones over all the years.
Phil is the owner and he's there every day so you'll definitely see him. I've been in there so much as a customer that he's become a personal friend. You tell him Jason sent you there, if you go. In the event, he's not sure which Jason (he may know more than one), make sure you tell him the one from the neighborhood that's in the Air Force now. Oh, tell him we'll go out for a beer on my next visit too... Thanks. ;)
