Most “citrine” sold as bright orange clusters is amethyst that has been heated. Natural citrine is pale yellow to smoky honey with even color. Heated amethyst is orange to burnt orange at the tips with a white, chalky base.

Is heated amethyst fake?
No. Both stones are quartz, and heating is a common, stable treatment. The problem is only the label. A fair seller writes “heat-treated” or “heated amethyst” so you know what you are paying for.
Three quick checks before you buy
- Look at the base. A sharp white base under orange tips points to heated amethyst.
- Look at the shape. A geode-style cluster sold as citrine is almost always heated amethyst.
- Look at the price. A large, vivid “citrine” cluster for little money is not natural citrine.
What about glass?
Glass imitations exist too. Glass often shows round bubbles, feels warmer in the hand and has perfectly even color. Quartz has a hardness of 7 and will scratch ordinary glass. See How to spot fake crystals.
Does it matter which one I choose?
Choose what you like and what you were told honestly. If the natural stone matters to you, ask the seller directly whether the citrine is heated, and buy from shops that state treatments. More in Where to buy real crystals online.
Does heat-treated citrine fade?
The orange color from heating is stable in normal use. Amethyst that has not been heated can fade in strong sunlight, see Which crystals fade in sunlight.
Is citrine safe in water?
Yes, for a short rinse. Citrine is quartz with a hardness of 7. Dry it afterwards.
