Dorje = Vajra? What is it?
Dorje is a ritual tool and spiritual implement which is symbolically used by Buddhism, Jainism, and Hinduism, all of which are traditions of Dharma.
It is also called Vajra in Sanskrit, which means diamond or thunderbolt in Tibetan Buddhism. This is because it symbolizes a tool, as hard as the diamond or as powerful as the thunderbolt, that can cut through ignorance, delusion, greed, anger, and impurities of the mind. It is also believed to represent the firmness of spirit and spiritual power.
Dorje and the bell
The Dorje is often used together with a bell during ritual and meditation, often at the start of a chanting session to clear the mind and create focus.
Always hold the bell in the left hand and the Dorje in the right. Ring the bell with your left hand or you can also strike it with the Dorje. The sweet sound of the bell resonates through the air, clearing the space and creating harmony.
Where do you place and work with a Dorje?

Some Buddhists perform ritual at home, they may place dorje at their sacred altar and work with it during their meditation and chanting.
