About Us

We're Gemstone Specialists

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 Cooper 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.

Allgem was the first to introduce the diamond simulant Cubic Zirconia into Australia and stunned local jewellers who could not tell the difference between it and the real thing.

The first Allgem retail outlet was opened in 1978 in William Street, Perth. In 1987 the Gryg’s took over another business at Shop 12 London Court. In 1992 Allgem added another larger store at the front of London Court under the clock in the Hay Street Mall and combined all three into larger premises.

Professional Qualifications

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 present 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.

The Grandchildren; Brendan, Sarah and Jason plan to get their diploma of Gemmology and to further their studies in graphic design and jewellery making within the next few years.
