A blaze of orange and gold crystal points, set up on a carved wooden stand like a little sculpture.

This cluster is heat-treated amethyst, which is how most citrine on the market is made. Heating turns the purple crystals deep orange, amber and lemon, often with pale washed-out tips. The cluster sits in a hand-carved wooden base that cradles it upright.

Citrine is nicknamed the merchant's stone and traditionally linked with abundance, optimism and success. That's why you'll often spot one beside a till or on a home-office desk. The fiery colour also warms up a room instantly, especially in afternoon light.

How to use it

• Set it on a desk or home-office shelf
• Place it near your front entrance
• Light it from the side to show the colour
• Pair it with pyrite or green aventurine

Care: Dust it with a soft brush, and keep it out of strong, direct sun, which can slowly fade the colour.
