Definition

Fine jewellery is jewellery made with precious metals such as gold, platinum or sterling silver and set, where stones are used, with genuine gems rather than glass or synthetic substitutes. The definition is a practical one: it is about the materials, not the price point. In Australia, fine jewellery is typically made in 9ct, 14ct or 18ct gold or sterling silver, built to last and retain value over time, unlike costume jewellery which uses base metals and is not expected to endure in the same way.

Frequently asked questions

What is the difference between fine jewellery and costume jewellery?
Fine jewellery is made with precious metals and genuine gemstones and is built to last, while costume jewellery uses base metals and glass or plastic stones, is made for fashion rather than longevity, and is typically much less expensive.
What is demi-fine jewellery?
Demi-fine sits between fine and costume. It typically uses sterling silver or gold-filled metal with lab-grown or semi-precious stones, aiming for a better quality than costume jewellery at a lower price than fully precious-metal fine jewellery.
Does fine jewellery hold its value?
Precious metal pieces retain intrinsic value tied to the metal itself, and pieces set with diamonds or coloured gems have gemstone value as well. Fine jewellery generally holds its value far better than costume pieces, though specific resale value depends on the piece, brand and market.
