Pyrite is often dismissed as “fool’s gold” but this mineral creates some of the most stunning crystals in nature. Walk into ...

Perhaps the crystals have a strange shape not typically associated with that mineral, suggesting a nefarious cut or polish.

The various materials, shapes and other aspects of watch crystals, however, require a bit more breakdown: Learn the Basic of Watch Crystal Materials The most common types of watch crystal materials ...

Using biominerals as an inspiration, Livermore physicist Jim De Yoreo and his LLNL research team have determined a key factor in how to manipulate the shapes of crystals.

It's also unclear whether the shapes contain the original crystal or mineral that formed them, or if those crystals dissolved away and were perhaps replaced by something else.

From a Celtic Wiccan crystal center in New Paltz to a museum-quality mineral collection in Columbia County, we found the best in the Hudson Valley.

The complex-shaped crystals of calcite were fabricated using a technique that involves depositing the mineral in a way that creates intricate microscopic patterns.

Scientifically speaking, the term “crystal” refers to any solid that has an ordered chemical structure. This means that its parts are arranged in a precisely ordered pattern, like bricks in a wall.

Like gloves, many individual mineral crystals or organic molecules exist in two mirror-image forms–a phenomenon known as chirality.

Intuitively it's not easy to think that a rainbow metallic crystal is actually the same kind of mineral as a black rough specimen, but these are both forms of hematite.
