Gemstone Index: Serpentine

Serpentine   is a lovely green translucent, waxy silicate of magnesium. it is often mistaken for various types of jade, and some stones called "jade" are actually types of serpentine. A major difference between the two semi precious stones is that serpentine is softer and less dense than most real jade. Its name comes from the word "serpent," or snake, perhaps because of its mottled green colors and patterns that can resemble snakeskin. Most of serpentine's history is tied in with the histo …

Gemstone Index: Jade

For centuries, the word jade applied to green gemstones brought to Europe from China and Central America. It wasn't until 1863 that society realized the term "jade" was being applied to two different minerals. These two gemstones, nephrite and jadeite, are relatively hard to distinguish from each other, and both are still called jade. Varieties of serpentine have also been confused with jade throughout history, and some serpentine is still called jade. In fact, the Chinese word for jade is appli …

Gemstone Index: Opal

Opal Gemstone Beads from Rings & Things: Opal beads have the same basic chemical composition as quartz, but usually contain 6 - 10% water.

Gemstone Index: Jasper

Gemstone Index: Jasper

Jasper is a semiprecious chalcedony (or microcrystalline quartz), and is usually red, brown or green. Its patterns are much less regular and defined than agate, the other chalcedony variety. Another difference between the two is that jaspers are generally opaque, while agates tend to be translucent (or at least contain translucent bands). This distinction stems from the stones' composition. Jasper contains microscopic "grains" of crystalline quartz and agate has microscopic "fibers" of crystalli …

Gemstone Index: Rhyolite

Gemstone Index: Rhyolite

Rhyolite gemstone beads can look very similar to jaspers, and the popular green variety of rhyolite is sometimes called rainforest jasper. Similarly, the type of rhyolite that displays red, yellow, brown, and pinkish spots is descriptively called leopardskin jasper. Rhyolites, igneous rock chemically identical to granite, have beautifully markings which originated when rhyolitic magma and lava cooled from a molten state too quickly for crystals to form. Rhyolite occurs largely in the U.S.A. Type …
