Definition
Chrysoprase is a variety of chalcedony quartz coloured by trace amounts of nickel, which gives it a vibrant apple-green to blue-green colour unlike anything else in the quartz family. It is translucent to opaque, takes a good polish and has been used in jewellery since antiquity, though it became particularly fashionable during the Art Deco and Art Moderne periods when its unusual colour paired beautifully with silver and marcasite. Australia is one of the world's leading sources of gem-quality chrysoprase, particularly from Queensland.
Frequently asked questions
- Is chrysoprase a rare stone?
- Good-quality, vivid green chrysoprase is uncommon, and fine gem material suitable for jewellery is less plentiful than other quartz varieties. Australia is one of the main sources, alongside Poland and Tanzania, and the best material commands a reasonable price for a quartz variety.
- Does chrysoprase fade in sunlight?
- Prolonged, intense exposure to sunlight can cause chrysoprase to fade, as the nickel compounds that create the colour are sensitive to UV light over time. Storing pieces away from direct sunlight when not in use helps maintain the colour long-term.
- What does chrysoprase symbolise?
- Chrysoprase is traditionally associated with hope, growth, new beginnings and a connection to nature, which aligns with its lush green colour. It has also been linked with good fortune and prosperity in various traditions.
