What our customers say

Great jeweller's in Dún Laoghaire! I went in just before closing time to ask about a watch strap adjustment. The jeweller was very helpful, unrushed and sorted out the problem which I now know can be fixed with a mini screwdriver. Very grateful to Costello's for sorting me out and for being so patient and helpful :)

Really friendly and helpful staff. I went in to get a new watch strap fitted and they couldn't have been more helpful.

No words can describe the time and effort these lads put into meeting customer satisfaction. Got some links taken out of my newly acquired watch, and I couldn't be happier with the result. 100% recommend this absolute gem of Dún Laoghaire.

Johnny was such a helpful gentleman, picked me a charm bracelet with a lovely angel charm on it. I will be back next Monday with my son for my anniversary gift. Can't wait — what a beautiful collection. Carol

Great jewellery store. Johnny has a terrific selection of beautiful stock and the prices are very reasonable. Also brilliant for repairing batteries and broken or damaged jewellery. Highly recommended.

Tiny little shop down a side street with a large and beautiful selection for everyone! They were fun to talk with and provided great service. Thank you!

Great place and fast service. I really do recommend this shop.

Prompt service! He changes batteries for watches on the spot — no need to wait ages. Friendly and priced well.

One of the oldest shops in Dún Laoghaire. Beautiful jewellery and great customer service.
