Blue Topaz is quite often treated to achieve the bright blue colour, especially in jewellery, although it is possible to find it naturally. Natural Blue Topaz is caused by the presence of iron atoms within the crystal lattice, whereas irradiating and subsequently heating colourless Topaz will permanently turn the gem blue.

Blue Topaz acts as a bridge between the Throat and Third Eye Chakras, promoting harmonious energy flow and facilitating effective communication and self-expression. It can also play a significant role in fostering self-confidence and a sense of self-acceptance, allowing individuals to feel at ease within themselves. It serves as a catalyst for clear and smooth communication, enhancing interpersonal relationships and connections. This crystal holds the power to expand one's mind and consciousness, encouraging openness to new ideas and perspectives. Blue Topaz nurtures spiritual connectivity, guiding individuals towards a deeper understanding of their spiritual path and facilitating a stronger link to the divine.
