Welcome to Costello Jewellers. Established in 1969 in Dún Laoghaire and now owned by Breasal Ó Caollaí for over 30 years we are specialists in gold, silver, platinum, diamonds and watches.
Please have a look around our website for jewellery and watches to get an idea of what you might like. But we believe that you can only decide and fall in love with your jewellery when you feel the weight and see the quality.
We want to help you with our professional advice.
Whether you are looking for something special for a birthday, christening, wedding
or anniversary — in fact, any occasion — we have the right present for you at reasonable
prices that suit every pocket.
Our jewellery ranges from Celtic to contemporary to nautical.
We are manufacturer and distributor of the Dún Laoghaire Ring ©.
Our motto is: If we do not have it in stock we will get it for you.
We repair your jewellery and watches, replace watch batteries, watchstraps and bracelets.
You receive complimentary engravings on items purchased and we guarantee all repairs and sales of jewellery and watches.
Costello Jewellers are conveniently located in the heart of Dún Laoghaire, just off Upper George’s Street beside Harry’s Cafe Bar and Dunnes.
