Sunny citrine is a vibrant yellow orange member of the quartz family. It is celebrated by jewellery designers for its hardness and resistance to scratches. The name is derived from the French for lemon, albeit slightly more orange than the colour of our favourite citric fruit. Thought to omit positive energies it has been claimed that citrine can alleviate depression and self-doubt, much like the sun’s healing rays are thought to counter such mood changes. Citrine is celebrated by some as the birthstone for November, along with topaz and morganite.
