The Brisbane Treasures competition by Xennox Diamonds celebrates the people, places, institutions, cultural works and traditions connected to Brisbane. The campaign marks the jeweller’s 50th anniversary and features a conditional Australian pink diamond prize valued at AUD $50,000. 💎
The proposed prize is an Argyle-certified natural pink diamond with a round cut, a weight of 0.14 carats, 5P colour and SI clarity. The terms allow substitution with a diamond of equivalent or greater substantiated retail value and comparable quality where reasonably necessary. The diamond is not guaranteed to be awarded.
If the diamond is won, the prize includes a personal jewellery design consultation with Xennox Diamonds. The winner can collaborate on a finished piece incorporating the diamond, such as a ring, pendant or earring. An allowance of up to AUD $2,500, inclusive of GST, covers design, craftsmanship, labour, gold and other standard manufacturing materials.
Additional gemstones, precious metals, design elements or manufacturing work beyond that allowance are at the winner’s expense following approval. The diamond must be incorporated into a finished jewellery piece; the prize does not provide the option of receiving it loose. Any unused manufacturing allowance cannot be exchanged for cash, store credit or other goods.
The major prize also includes the proposed provision of 12 months of Q Report jewellery insurance for the completed piece. Xennox Diamonds pays the first year’s premium, subject to the insurer’s eligibility, underwriting and policy requirements.
If the major prize contender does not win the diamond, that participant receives a $5,000 Xennox Diamonds gift card. The other four category winners each receive a $2,000 Xennox Diamonds gift card, regardless of whether the diamond is awarded.
