Durability is the most important factor in deciding whether blue topaz crystal can be worn every day or not, as blue topaz possesses good hardness, ranging from 8 on the Mohs hardness scale. This makes the gemstone suitable for everyday wear, but it’s important to remember that even though it is hard, it can still have a chance of damage. Everyday jewelry pieces like rings and bracelets expose the gemstone to potential knocks and scratches. In spite of its hardness, the crystal may still chip or scratch if it comes across sharp blows or rough handling. Therefore, wearing blue topaz jewelry every day needs some care to prevent damage.
