Blast From The Past!
These Jogia Diamonds television ads aired in 1987 on Perth television. Apologies for the quality, as they have been recorded from almost 20 year old VHS tapes.
This Good Morning Perth segment from the early 1990s featured Jenny Seton and Eoin Cameron, complete with chicken, telling really, really bad jokes about chickens. The segment was to promote The Great Australian Chook Raffle, which featured a "chook" brooch (which was really a rooster) provided by Jogia Diamonds as one of the prizes.
