Gemstone Jewellery Specialists in Australia
Allgem Jewellers is a family-owned business which has been supplying specialist services to Perth retail jewellers since the 1970s. Allgem founders, the Gryg family, are experts in precious gems and Australian opals. Joseph and Bessie Gryg began mining for precious gems in 1960, travelling to mines in Anakie, Sapphire, Emerald and Rubyvale in Queensland looking for sapphire.
They also travelled to Lightning Ridge, mining for black Australian opals and then to Coober Pedy and Andamooka looking for white Australian opals. They eventually settled in Western Australia, setting up business as wholesalers, supplying retail jewellers, cutting precious gems and carrying out jewellery work throughout the 1970s.
Founders Joseph and Bessie Gryg along with their son Alfie have extensive training and experience with precious gems and Australian opals, and have qualifications in the fields of Master Jewellers, Gemmologists, Registered Valuers and Diamond Graders.
Joseph Gryg completed his Fellowship of the Gemmological Association of Australia (FGAA) in 1974 and was president of the Gemmological Association of Western Australia for two years.
Bessie Gryg was the top graduate in Australia when she completed her Diploma of Gemmology in 1977 and was a practical demonstrator for the GAA. Bessie also studied jewellery design from the Gemmological Institute of America and has achieved her British Gemmological Diploma (FGA).
Alfie Gryg completed his Diploma of Gemmology in 2005 and was the president of the Gemmological Association of Western Australia for two years just like his father. He has also completed his Jewellery & Gemstone Valuing course which has allowed him to be a registered Valuer since 2007.
“I had a ring made here and I am very happy with the result. It’s a family business with the work being done on site. Happy with the product and service. The store is full of beautiful gemstone jewellery.”
“The staff were all great and very approachable. 10 out of 10 we will come here instead of going to franchise/big brands if we want to buy or fix jewellery, based on our own experience.”
This shop is run by the friendliest family In the world!
Any help you need I would recommend here about jewellery.

How do I Care For My Jewellery?
Jewellery is meant to be worn and appreciated by the owner. If you are concerned about the wear-and-tear of your jewellery, then bring it to us and we will advise you of the correct manner in which items such as precious gems, Australian pearl and opal jewellery or diamond engagement and wedding rings should be worn.
We do not recommend that you leave your diamond engagement ring or best jewellery on during manual labour just as you generally do not wear your best clothing. Jewellery is made of precious metals such as gold, platinum and silver that are malleable into chosen designs and have precious gems set into them easily.
Gold and platinum are called noble metals as they are extremely resistant to attack from chemicals and are unlikely to tarnish. Lower gold alloys such as 9ct gold and sterling silver have higher concentrations of copper and other reactive metals and can discolour over time or in contact with certain chemicals. The oxidation of the surface can easily be removed by treatment with a tarnish removing solution and may also require buffing with a cloth or more professional polishing.
The type of precious gems that are set in the jewellery item and the manner of setting can also determine the fashion of restoration. Jewellery cleaners can have acidic, alkaline or alcohol based ingredients. Most precious gems and gemstones will not be affected by the cleaners but if unsure, please bring it to us for advice.
How do I Store My Jewellery to Prevent Damage?
Store your jewellery and precious gems in a way that prevents different pieces from scratching one another.
Just as gold alloys are of different hardness, precious gems vary significantly and even the points of precious gems can scratch others due to abrasive hardness. The ideal solution is to keep it in a box with separate compartments.
How do I Get Her the Correct Ring Size?
If you are selecting a diamond engagement or wedding ring, there are several ways to find the correct size:
- Make an impression of a current ring in a bar of soap ensuring the intended diamond engagement or wedding ring is for the same finger;
- Trace the inside of the ring onto a piece of paper to obtain the internal diameter;
- Place the ring on your finger as far as it will go and then mark it with a pen;
- Have a friend of hers ask her finger size as a matter of curiosity.
However, the safest way is to bring us one of her rings with the explanation that you are having it cleaned and checked. We can size a diamond engagement or wedding ring from this.
What is your Returns, Exchanges, and Warranty Policy?
Exchanges: We can offer an exchange within 7 days after the purchase. We cannot exchange the item if it has been altered or damaged in any way. If the item chosen for exchange is cheaper than the original item, a store credit is issued. A store credit is only valid for 12 months.
Warranty: We have a 12-month warranty that only covers manufacturing errors. Harm, or wear/tear caused by the customer is not covered by warranty. Our experienced jeweller will examine the item thoroughly to determine the cause of damage.
Buy-backs: We legally cannot buy back any jewellery items we’ve sold as we do not have a second-hand license.
Product aftercare: We advise the all jewellery shouldn’t be worn in rough activities or cleaning. Opal triplets and doublets must not be submerged in hot soapy water. Do not spray perfume or use moisturises around jewellery as this discolours metals and/or damages the stone (especially pearls!).
How much does Allgem charge for jewellery valuations?
Allgem does not charge evaluations 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 with all tests from $100. 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.
Identification Fee (No Valuation) starting from $55 for colourless stone, $85 for single coloured stone
Booking valuers time to go through many articles (inhertied jewellery) to determine if they are genuine, fakes or worth valuing. Starting fee of $50. Valuation charged separately.
Allgem Jewellers strictly do not give “off-the-cuff” estimations on jewellery articles.
All our evaluations are done on premises in our secure workshop by Alfie Gryg (Valuers Number WA075). Please allow 2 to 3 weeks (depending on how many items are left). We provide a photo valuation with retail replacement value.
