Take a pill for what ails you, or clutch a crystal? A-listers are deploying gems for everything from increasing positive home energy (Kate Hudson, Victoria Beckham) to decreasing performance anxiety (Adele grips one during concerts). "I definitely see an increase in crystal use," says meditation guru Olivia Rosewood, whose clients include stars and moguls. While there's no medical proof — studies on crystals have proved only the power of suggestion or a placebo effect — many cultures have histories of them purportedly healing via energy vibrations. "An intellectual understanding is not required to feel peace instantly," says Rosewood. "I attribute crystals' current popularity to increased stress and their inherent calming power."
1, 7 — Rose & Clear Quartz
Katy Perry carries rose quartz for love, "a feel-good stone," says Michael Carbaugh, founder of L.A.-based Sandoval, which sells scents containing crystals ritualistically charged by the full moon.
2, 4, 6 — Black Tourmaline, Pyrite, Hematite
These gems and others are embedded under the sprung-oak floor of movement guru Taryn Toomey's new NYC studio opening in January. Jennifer Aniston and Kate Hudson attend sessions of her cultish The Class, held daily in Santa Monica and Hollywood.
3 — Amethyst
Some of Rosewood's clients use infrared-heated, crushed-amethyst-filled "BioMats that cover an entire bed," she says of the $1,695 pad that harnesses technology NASA uses to help astronauts regain vigor. "It's deeply relaxing and life-changing for sufferers of chronic pain."
5 — Malachite
Renate Radford, senior vp of TV for Elizabeth Banks' Brownstone Productions, says writers rub stones to cure anxiety. "I work with a big writer who carries around a malachite stick," she says. "Creative people are more open to trying different things, and all this stuff is imbued with the magic you give it."
