"I do so love a functional accessory."This trope is for accessories and jewelry that don't just look pretty, but do stuff! There's a common "formula" behind the making of a Magical Accessory; you take a Power Crystal with superpowers and hire the Ultimate Blacksmith to cut it and embed it into a mystic silver setting. This Super Trope covers just about any Glowing Gem studded piece of sparkly magical jewelry that has or grants powers and effects. Because humans are historically quite good at making bling, there's a lot of tricked out trinkets this trope covers. From top to bottom, they are:
— Rarity, My Little Pony: Friendship Is Magic episode "Power Ponies."
- Hat of Power: Includes crowns, circlets, diadems, and tiaras. Examples of these should go there.
- Earrings: being on the ear itself and jewelry they naturally lend themselves to themes such as super hearing, illusion and Glamour based abilities.
- Necklaces and chains: Cover the entire spectrum. Special mention goes to Orphan's Plot Trinket, which this frequently doubles as.
- Armlets: Usually grant Super Strength.
- Bracelets: Tend to be Amplifier Artifacts that boost spellcasting. Examples may fall under Super Wrist Gadget and Gadget Watches.
- Ring of Power: Do anything and everything, sometimes literally in the case of the Green Lantern Ring. Examples of these should go in their respective tropes.
- Belts and belt buckles: May grant super strength or Nigh-Invulnerability. Compare Utility Belt.
- Anklets: Usually give Super Speed.

- A recurring motif in the Deryni works:
- Haldane empowerment rituals use a number of different pieces, starting with a single ruby earring called the Eye of Rom. Rhys Michael Haldane pressed an enameled brooch into service for a self-designed triggering of his powers; this piece was used later in the timeline for the more structured rituals of his successors. Donal Haldane used a silver bracelet to encode his son's ritual; Alyce de Corwyn Morgan triggered part of the process on her deathbed, and her son Alaric finished it years later.
- Brion Haldane commissions a new ducal signet ring for Alaric Morgan (reflecting his personal coat of arms, a blend of those of his parents), This ring becomes a Ring of Power, at one point magically securing items for Brion's son's ritual as well as securing the door of Morgan's study.
- Technological version: in Hard to Be a God Don Rumata (a disguised observer from a spacefaring Earth on a medieval planet) wears a circlet with a single large gem. The gem is actually a camera and the circlet contains a one-way communicator that constantly transmits camera footage to mission control. He uses it to transmit his intelligence data and to alert other observers in case of danger. it's because of this device Earth forces arrive in a nick of time in the finale to evacuate Rumata when he goes against his directives and puts himself in mortal danger.

Several of the Forsaken also had angreal in the form of rings.
