Common prop used by witches, Fortune Tellers and psychics (and Hollywood Romani) for fortune telling, scrying, and long distance communication. Most commonly it's a dinner plate sized sphere of clear glass, but these can be of just about any size and material, so long as they're shiny.
- Konoka and Anya in Mahou Sensei Negima! sometimes use these (strange in Konoka's case, since she uses eastern-style fortune telling). Evangeline uses hers to communicate over a long distance like a phone.

- In My Little Pony: Friendship is Magic (IDW) Queen Chrysalis used one to communicate with the Mane Six, telling them to confront her in three days. It even provides a map. She also uses it as a means of surveillance and source of entertainment, since the heroes land in all sorts of trouble along the way.

- Dungeon Keeper Ami: Used for communication, as revealed in Deal with the Devil:
Her gaze turned to a round object sitting on one of the lab benches when she felt the magic around her react to it. The crystal ball, for it looked as if it had emerged straight from a fortune teller's tent. A glowing white nimbus surrounded it, and fog within was swirling to form a face.
One of the devices in [Nicodemus Asbraxe's] study alerted him that a Keeper was searching for some unspecified item, and the fence quickly pulled his hood down until his face was hidden in a pool of darkness out of which only a long, mangy beard protruded. He then muttered a well-practised incantation, and a picture formed in the air above his coffee table, showing him the prospective client[.]
- In Heart of Ashes, the witch Andraya gives Smaug a crystal sphere which he uses to track Kathryn down to Vathvael. The sphere is later used by Freyja and Faervel to track Smaug and Kathryn down to their hiding place in Emyn Muil.

- The Thief of Bagdad (1924): A crystal ball shows the Prince of India that the princess is ill.
- The Thief of Bagdad (1940): The All-Seeing Eye that shows Abu where to find Ahmad.

Fortune Teller: [peering into his crystal ball] Ahh, you have a wonderful future. I see a man in your life.

- The Lord of the Rings has the palantíri, a set of seeing stones that allow the viewer to scry far off locations and communicate between each other. Of course, some were destroyed, and one fell to Sauron, making their use incredibly dangerous considering his penchant for Mind Rape or Mind Control.
- Middle-earth has a few other clairvoyance-granting artifacts. The Mirror of Galadriel (actually a basin filled with water) could show things from the past, present, and possible future. The seat at Amon Hen allows one to see far-away present events, and, while never explicitly stated, its counterpart at Amon Lhaw presumably does the same for hearing.
- Parodied in Bored of the Rings with the mallomar, "the magic watchamacallit of the elves." Moxie thinks it works like a Ouija board, but it's really a glorified Magic 8-Ball.
- Harry Potter:
- Averted as far as Divination goes. Professor Trelawney "teaches" the use of them as part of her class, but no one ever actually sees the future in them. In the third book, Harry runs out of patience during his Divination exam and claims to see Buckbeak the hippogriff flying away to freedom — which he ends up doing, albeit with a passenger.
- The Ministry of Magic has a whole library of similar glass spheres, except they act as storage devices for recorded prophecies. This room is the site of a battle in book five, during which several are smashed.
- Pensieves fulfil are similar function, enabling the user to store and relive memories. And the memories in the Pensieve (when not actually using it) are described as halfway between silvery water and gas.
- Large shiral crystals are used this way in the Deryni works. Alaric Morgan has a fist-sized one in a golden gryphon holder in Deryni Checkmate, and the Camberian Council have a larger one suspended from the ceiling of their meeting chamber.
- The windows of The House in The Redemption of Althalus serve this purpose.
- Used both straight and subverted in Discworld novels.
- Wizards often complain they can't get good reception on them (ironically enough, using it to watch a rock concert in Soul Music). Witches and mediums such as Mrs. Cake only use them when paying customers hang around, but in the privacy of their own house they can use bits of glass or water or anything else they like.
- Wizards have refined the crystal ball concept to create the "omniscope". They used one in Going Postal, with this result:
Ridcully: It's not working, Mr. Stibbons! Here's that damn enormous fiery eye again!
- The first time Granny Weatherwax uses a crystal ball, in Equal Rites, she strongly distrusts the thing, since it seems like wizardry.
Granny: Never could get the hang of this damn silicon stuff. A bowl of water with a drop of ink was good enough when I was a girl. Of course, we had to make our own enchantment in them days.
- Nanny Ogg uses a glass net floater one of her sons brought back from a sea voyage. It works, but everything is tinted green.

- In The Riftwar Cycle, the first sign that Pug had potential as a magician came when he inadvertently saw something in a crystal ball.
- Called a Gramerhain in the Bahzell Bahnakson Series, and far more limited than most. The victory in the third book probably wouldn't have happened if they'd been as omnipurposable as most crystal balls.
- In Robert E. Howard's Conan the Barbarian story "A Witch Shall Be Born" the title witch holds this in contempt as a means to study, but uses it for communications.
I could never endure to seclude myself in a golden tower, and spend the long hours staring into a crystal globe, mumbling over incantations written on serpent's skin in the blood of virgins, poring over musty volumes in forgotten languages.
- In Gene Wolfe's The Sorcerer's House, the psychic has a fake crystal ball that sees good stuff and the real thing.
- One of the talking magic items Aahz collects in Myth-Gotten Gains is a crystal ball, in which the face of a female of the observer's species manifests when it's communicating with people.
- In Cerberon, these are called scryballs. They are used to view other locations, communicate with other scryballs like a telephone, or to spy through uncovered scry balls. Aladavan keeps a miniature scry ball on a chain around his neck, which he keeps under his shirt when he's not using it. He's able to easily spy on and track Thedrik because his sword has a small scryball on the pommel, which Thedrik never covers. Scryblocks are employed to prevent people from using scryballs to spy on them, and to protect against mental eavesdropping.
- In the Dungeon Punk world of Tales of MU crystal balls are used like computers, forming an "aethernet" even.
- In Victoria Hanley's The Seer and the Sword, a crystal is need to trigger Torina's abilities.
- A variant combining the Crystal Ball and lot-casting concepts crops up in Michael Reaves' The Shattered World: the "casting sphere". Used by inhabitants of the still-liveable, orbiting fragments of a fantasy world that broke apart long ago, such spheres are constructed of pieces of polished wood, coral, ivory or crystal, that fit together like a 3-D jigsaw. Each piece represents one of the fragments; when the hollow sphere is dropped, its pieces scatters into patterns from which future events can be divined.
- A variant is seen in the Enchanted Forest novel Dealing With Dragons in the form of The King's Crystal. Owned by the King of Dragons, it actually took the form of a crystal plate and was used for divination and scrying. Heroine Cimorene expresses surprise over it not being a traditional ball shape, only to be told by Kazul that the odd shape gave it more range and power.
- Battlestar Galactica has a prophetess in New Caprica use a bowl of water to divine the future for Number Three. Then there's the Cylon's Unusual User Interface, which consists of placing their hands in streams of water; and the prophetic Hybrids in the baseships, who are submerged in water.

- In "Family", Buffy can't decide what to give Tara for her birthday. Because she's a witch, Xander suggests a "cheesy crystal ball" as a present, only to learn Giles already has one wrapped. At the birthday party we see Tara faking a smile as she unwraps the ball. According to Anya crystal balls were popular with amateurs, which explains why an experienced witch like Tara isn't impressed by them.
- In "Hells Bells", Future Xander uses one to show his younger self the Bad Future that awaits him if he marries Anya. He's actually a vengeance demon out to ruin their marriage with illusions.
- An Orb of Thesulah can be used to hold someone's soul (or serve as a New Age paperweight).
- Iron Maiden's "Can I Play With Madness?" is about a man going to a prophet with a crystal ball — in which, for the man himself "there's no vision there at all". In fact, Seventh Son of a Seventh Son (the album that song is on) is a concept album about a man blessed and/or cursed with prophetic sight by virtue of his being, well, the seventh son of a seventh son.
- The protagonist of the Running Wild album Black Hand Inn uses his crystal ball to "tell tales of past and future" in the eponymous inn. It also comes in handy in privateer business, as it shows where "he has to steer".

- Palantir can generate magical balls to do things, as said in The Three Little Witches:
Palantir shook her head. "How're we gonna do that, with all the detention we got? I got a much better way!" She cupped her hands before her and...
"Oh. THIS again," Abra grumped.
"You're just jealous 'cause you don't have a natural gift for this sort of thing."
"Sure, sure, Im all green with envy, 'cause you're the Goblin King from Labyrinth, David Bowie," Abra mocked.
Palantir concentrated on the magic ball, which glowed. As the three of them peered into it, an image of a low-slung rock in front of a gray-painted sheet of metal set into a hillside. A strange pale flame flickered over the rock. "That's IT!" Palantir said with a triumphant smirk in Abracadabra's direction. Using a general sense of proximity that she got from the ball, Pally led them through the gloom. They walked quite a ways, and Clover was starting to complain about being tired when Palantir said, "There it is!"
"Where's that fire we saw in the crystal ball?"
- Twitch (Tek Witch) from Generation 2, in Following the Path of Cute, as she's a witch. Not Really. She's using it to look for invisible bunnies:
"I made a crystal ball..." She proudly held up what appeared to be a crystal ball, about the size of a softball.
"It sure looks like a crystal ball," Tyler agreed. "What is it really?"
Michelle hesitated a moment before answering, "It's an omnidirectional camera and monitor unit."
"If there are any invisible bunnies in here, I'll be able to see them..."
- Palantir can generate magical balls to do things, as said in The Three Little Witches:
- Madam Wu in Avatar: The Last Airbender heats bones and studies the cracks. Aang has such a huge destiny his bone explodes.

(He already knew about Ozai, after all.)
- In the ALF cartoon episode, "Housekeeping for Pokipsi", Madam Pokipsi the "Fortune Smeller" has a Magic Ball that is not only use for divination, but is the source of all her arcane powers; when Gordon messes with it, he ruins her magic tricks ("Vhat haf you done ma Crystal Bawwwwl, Yunk Mayun?").

- The Duke's "Viewing Stone" in Gawayn
- Rocky and Bullwinkle: "Eenie, meanie, chili-beanie! The spirits are about to speak!"

- In Season 9 of My Little Pony: Friendship Is Magic, Grogar employs a magic sphere looking very similar to a Palantir — except the "iris" part is vertical, like a goat's, unlike the common slitted "eye of Sauron" representation. With it, he provides shadow imagery of the past to illustrate his backstory, and witnesses Sombra's defeat at the hooves of the Mane Six. Presumably, it's this artifact that allowed him to stay updated of the latest events in Equestria, including the deeds of the villains he gang-pressed in his service, as well as the modus operandi of the heroes.
- Practitioners of modern ceremonial magic and some forms of witchcraft use crystal balls. Rather than expecting to see anything in them like a TV set, you are supposed to use them simply as a focus of attention, similar to meditation. Anything you see should appear in your mind, not in the crystal.
- This trope was played straight in earlier occult schools, such as those popular during the 16th and 17th centuries. During this period, occultists believed they could summon spirits like angels into crystal balls, who could give them spiritual visions, or converse or bargain with them.
