Trust Your Repairs to Allgem

Finding somewhere you trust to clean and repair your precious gems and jewellery can be a difficult task. Most stores send their repairs to an outside ‘trade jeweller’ for work to be completed.

That means if you want gold jewellery repairs and you live in Perth, your valuables may be sent to the eastern states and pass through several hands.

At Allgem, all jewellery repairs are carried out in a workshop located beneath the retail store, ensuring your valuables do not leave the premises and are kept secure always.

Allgem’s Jewellers have more than 45 years’ experience in the trade and will repair most types of jewellery, from modern to antique. Most jewellery repairs take between 2 and 14 days, depending upon the complexity of the job and time of year. You will be given a quote and estimated finishing time before any work has begun.

All jewellery repairs carried out at Allgem are fully guaranteed and of the highest quality. Allgem has built a reputation for quality workmanship and receives many referrals from happy customers to their friends or family.

Ways to Combat Jewellery Wear and Tear

Quality jewellery should be checked, cleaned and maintained on a regular basis to retain its appeal.

The team of master jewellers at Allgem can restore your precious gems, coloured stones and jewellery to its original condition and guarantees the quality of all work carried out.

Jewellery repairs and restoration are usually required as a result of wear and tear.

Coloured stones may become chipped, clasps may break and surfaces will get scratched. Metals such as silver, and gold can tarnish and most jewellery becomes dirty over time with general wear.

Claws especially, can wear down over time and this may cause your beloved stones to loosen and perhaps be lost. Specialised jewellery repairs for building up individual claws, re-tipping or even the replacement of the entire claw may be necessary for stability and safety of the stone.

Reinforcing Rings

Engagement rings are generally worn against a wedding or eternity ring. Over time, the engagement and other rings will rub against one another and eventually wear away the metal leaving them very fine, especially at the base.

The same thing can happen to the terminations of chains/bracelets, or any other jewellery pieces where movement against itself or other pieces is unavoidable. (E.g. pendants sliding around on a chain).

The jewellers at Allgem can reinforce the bands on engagement and wedding rings, gold rings and other decorative rings to provide the necessary strength, especially when supporting precious gemstones. It is important that jewellery pieces containing precious gems and other stones including Australian opals, pearls and diamonds are repaired correctly as an inappropriate restoration may weaken the jewellery setting or damage the stone.

The jewellers at Allgem can also build up worn away sections on gold and silver clasps, jump rings, pendants, and chains or bracelets.

Replacement of precious gems including the diamond in engagement and wedding rings

Allgem does not charge valuations by a percentage of article. As an example, a 1-carat genuine diamond solitaire ring will be charged at a starting fee of $300 to value without original documents. Simple coloured stone jewellery with all tests from a minimum of $220. Multi set jewellery pieces are more time consuming, therefore more expensive to value. For exact quotes, the registered valuer would have to have a look at the items in person. Some items might be very old, worn and embedded with dirt. It this case the jewellery has to be cleaned in order for the jeweller to even determine the type of gemstone he is looking at.

Gem Identification Fee (No Valuation) starting $85 for single coloured/colourless stone. 

You can drop items in anytime 6 days a week (We recommend calling beforehand, to make sure the valuer is working that day). 

Currently we take Valuations on for a 4-6 week duration.
