A Daywalking Amulet is a piece of jewelry with a Lapis-lazuli gemstone enchanted by witches, to allow vampires to walk freely in the sunlight, The witch who casts the enchantment can also temporarily or permanently undo the spell on the jewelry at their discretion. Throughout the series, female vampires often wear bracelets, necklaces, or rings that possess a Lapis-lazuli gemstone, as opposed to male vampires, who usually just wear rings. The jewelry itself doesn't have to be worn as it was intended; as long as it the vampire is touching or holding it in some way, they are protected from daylight. The charm placed by witches over the gemstone is not dependent on the caster, since the Lapis-lazuli jewelry has been known to protect their vampire wearers long after the witch who spelled it have died. It was implied by Katherine that the enchanted jewelry only protects the vampire for whom it was made by the witch who cast the spell. Though vampires with daylight amulets are fairly common in the series, there are still many vampires who do not possess them, since most witches are not fond of vampires, and for that reason usually aren't willing to make them daylight amulets. Very few humans are aware of the existence of daylight amulets, either, which gives vampires the advantage of walking in the sun, avoiding suspicion from most humans who still believe vampires can only walk at night. When Stefan and Damon were interrogated about how they walk in the sunlight on separate occasions by Sheriff Forbes and Logan Fell, they both refused to tell their secret.
- In the books, it seems that the power of Lapis Lazuli is transferable, as Elena wears Katherine's ring without any problems.
- In the series Stefan's Diaries, Lexi actually borrows Stefan's ring. These books are based off of the TV series.
- In the series, it seemed to be non-transferrable, as when Lexi asks to borrow Stefan's ring in 162 Candles, he states "you know it doesn't work that way".
- In American Gothic, it was confirmed that daylight rings are not transferable. Elena in an attempt to look more like Katherine, asks her to hand over her bracelet. She claimed that she couldn't because it was daytime and she needed, and added that it wouldn't work on her anyway.
- The stone bears some similarity to the Gem of Amarra from the Buffy and Angel franchise. With the only difference being that the Gem protects Vampires from demise, whilst the Lapis Lazuli keeps them from burning up in the Sun
