What is jasper?

Definition
Jasper is an opaque, fine-grained variety of chalcedony quartz that forms in virtually every colour, with reds, yellows, browns, greens and multi-coloured patterns all common. The colour and pattern depend on the minerals and organic matter that were present when the stone formed, which is why jasper varieties differ so dramatically in appearance. It takes a good polish, sits around 6.5 to 7 on the Mohs scale, and is used in beads, cabochons, carved pieces and statement pendants. Australia has its own celebrated variety called mookaite, known for its rich reds and yellows.
Frequently asked questions
- What are the different varieties of jasper?
- There are hundreds, but well-known varieties include red jasper, which is warm brick-red from iron content; ocean jasper, which shows round orbicular patterns in greens and pinks; picture jasper, which has landscape-like brown and tan patterns; and mookaite, an Australian jasper in deep reds, purples and yellows.
- What does jasper symbolise?
- Jasper is traditionally associated with nurturing, stability and a connection to the earth, which reflects its earthy colour range and its dense, grounded feel. Red jasper in particular is linked with strength and courage in many crystal healing traditions.
- How durable is jasper in jewellery?
- Jasper is a practical stone for most jewellery styles. Its hardness of around 6.5 to 7 means it resists everyday scratches reasonably well, and it is tough enough not to chip easily. It is at home in pendants, earrings and bracelets and can be worn in rings with a little care.
