Products & Services
At Troy O’Brien we aim to put the elegance, art and romance back into jewellery design.
To create your own unique piece of jewellery, we take the time to understand your needs, lifestyle and budget. We then combine your ideas with ours to create a design that is beautiful, practical and enjoyable to wear.
In addition to our diverse selection of loose gemstones on-site, you can also view specialised stones on a sale or return basis.
We will explain all that there is to know about diamonds and other precious stones, so that you can choose with confidence.
Troy O’Brien custom made jewellery:
• is all hand-sketched first
• can be made by hand or designed on computer (CAD).
CAD – computer aided design
Using the most up-to-date computer technology we can transform even the most complex jewellery ideas into reality with far greater accuracy and in less time than ever before.
100% delight guaranteed
Unlike most jewellers, we sit down with you before the final stone setting to ensure the size, design and fit is perfect for you. With Troy O’Brien there are never any unwelcome surprises.
Benefits of our on-site manufacturing
As all manufacturing work is carried out on our premises you:
• view your special piece before completion and as part of this process
• can request a photographic story of all stages of creation.
• enjoy best pricing as there are no middle men involved.

To ensure your complete peace of mind, your Troy O’Brien jewellery is stamped with four hallmarks.
The first is the Troy O’Brien Maker’s Mark, our signature and guarantee of quality materials and excellence in craftsmanship.
The second is the Metal Purity Mark or carat stamp to confirm the purity of the metal or gem.

Expert valuations and advice
Our expert gemologists can appraise your jewellery to let you know the true value and quality for insurance.
We offer a complete service at a flat rate regardless of the jewellery's value, including:
• thoroughly cleaning and checking all pieces
• measuring and testing stones to the extent that the setting permits
• photographing and weighing each piece for identification
• arriving at a fair replacement value for insurance
• advising you of any repairs or attention required.
Contact us today to have your jewellery professionally valued.
If you own jewellery that you treasure greatly, we highly recommend having it inspected, cleaned and polished once a year. In particular:
• claw-set jewellery, to ensure the gemstone is secure
• gemstones, to remove surface scratches and chipping
• rhodium plating of white gold jewellery to maintain its crisp appearance.
White gold alloys consist of pure yellow gold mixed with other white alloys such as platinum, palladium and silver. Rhodium plating replaces the dull, grey and, in some cases, yellow tone, with a white reflective finish. Platinum metals can be cleaned and polished without rhodium plating.
