We love our community and are proud to serve Lancaster County! Nothing means more to us than⁠ your health and safety. In light of the recent updates regarding COVID-19, we are posting to inform you that effective at closing, 6pm tonight, we are closed in compliance with the statewide shutdown issued by Governor Wolf. 

If you have jewelry here for repair or any other reason, it will be locked up in our vault. It will be safely stored until we open our doors again, at which point, you will be able to pick it up.

We look forward to the days ahead when we can serve you once again!

It's Our Favorite Day of the Week! The day we get to show off yet another amazing Koser Couple! "Kyle and I met 6 years ago up at my college through mutual friends where he told me he was going to marry me one day. I thought he was crazy. For the next 2 years every time he saw me he would make sure to tell me we were getting married and I still had no interest. Finally in 2016 I gave him a chance after pursuing me for so long. I guess he was right all along, he was going to marry me! October 12th, 2019 was the best day ever." Congratulations Kyle and Nicole! We wish you a lifetime of happiness!

It's Our Favorite Day of the Week! The day we get to show off one of our amazing Koser Couples! "It was a Saturday like any other day and Michael wanted to go for a motorcycle ride. He suggested we take his go pro and I just figured it was to get footage of us riding. We went to the river and then he took me to high point trail in York. I still had no idea at this point. While we walked up the trail he asked to get a picture multiple times which started to make me a little suspicious because he was never the one to ask to take pictures. We sat on a bench and talked for awhile and then he asked to get up and get one more picture that he acted like the go pro was taking but it was actually recording a video the whole time! The second I saw him pull out the box and kneel down I burst into tears. Of course I said yes and I couldn’t stop crying happy tears for about 3 days. It was perfectly romantic and special between just the two of us." Congrats to our friends, Michael and Becky!
