Bismuth crystals

The Trippiest Rocks You Ever Did See

Iridescent, glimmering, and trippy, gemstones at their most eye-catching possess a riveting allure. It's no surprise that, for thousands of years, people have coveted these striking bits of mineral and crystal, and have often invested them with supernatural powers. Behold — the beauty that's created when atoms align.

Amethyst. A Schneider Mark

Deep Violet Amethyst

The most prized crystal of the quartz family, violet amethyst's name derives from the Greek, "amethystos," meaning "not drunken," as the crystals were thought to prevent drunkenness. Violet amethyst owes its saturated purple color to, among other things, exposure to iron impurities within its prismatic structure.

Green Malachite

Resembling something that might have originated on another planet (Krypton, perhaps?), this striking green chunk of malachite's unusual texture is called botryoidal, from the Greek "botrus," or "bunch of grapes."

Stibnite

Also known as antimonite, this mineral is a sulfide, i.e., more like a precious ore than a pure gem. With it's glittery appearance, it was the original eye cosmetic of the ancient Egyptians; men and women used it to darken their eye-brows, line their eyes, and color their lashes.

Titanium Aura Quartz

Stationary electric charges create this iridescent rock. With its appearance like a psychedelic mountain range, this quartz is considered one of the strongest crystals around by New Age healers. With its eye-popping energy, it's not surprising some consider it the antidote to sluggishness and fatigue.

Precious opal weisschr

Precious Opal

Classified as a "mineraloid," opal doesn't form in the precise, faceted way that some silica-based minerals like quartz so often do. Opal's coloring, meanwhile, is the result of its diffraction of light: that is, its surface causes light waves to bend and reflect back in unusual ways. A semi-transparent stone, opal essentially alters the color spectrum of light that passes through and around it.

Flourite Crystal

A beautiful mineral with multiple utilitarian uses (it's used in the making of some types of glass and some enamels, for example), flourite lent its name to the phenomenon of fluorescence; under ultraviolet light, some minerals will appear to glow with colors not visible in normal light.

Bismuth

Bismuth is a brittle and crystalline heavy metal, with a rectangular structure that only forms when the metal is slowly cooled in a laboratory — never in nature. Compounds and alloys of bismuth are used widely in cosmetics, medicines, and many other commercial and industrial applications.

Bi-Color Tourmaline

A semi-precious gemstone (more prosaically: a crystalline boron silicate mineral), tourmaline comes in a variety of colors sparked by compounds found within, like aluminum, iron, magnesium, sodium, lithium, or potassium. Bi-color tourmaline, like the example pictured here, is rare and can sell for as much as $1,000 a carat when cut and faceted.
