Tourmaline (dravite) crystal exhibiting the Usambara effect from Nchongo, Umba Valley, Tanzania. Usambara color change is different from "alexandrite effect," which is color change dependent on type of light.
Single Dravite crystal exhibiting the "Usambara effect" color change (named after nearby mountains). This is a different type of color change than the Alexandrite effect, where the color changes in different types of lighting. In this case, the Dravite crystal appears green in normal lighting, however when a single light source is transmitted through the crystal, at a certain thickness, a sudden color shift from green to red is observed, while less thick areas remain green.

Zultanite is one gemstone whose amazing natural color changing abilities makes it well suited to savvy jewelry connoisseurs.
Zultanite, a gem variety of diaspore, only occurs in the mountainous region of Anatolia, Turkey. The gem exhibits the optical property called “color change.” Zultanite gems turn from yellowish-green to purplish-pink depending on the light source. Sizes over 5 carats are very rare. Gem quality crystals were first discovered in the early 1980s.

Calcite (CaCO3) Bizarre nailhead calcite stalactite from Hilton Mine, Cumbria.The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380-470°C, and vaterite is even less stable.Calcite crystals are trigonal-rhombohedral, though actual calcite rhombohedra are rare as natural crystals. However, they show a remarkable variety of habits including acute to obtuse rhombohedra, tabular forms, prisms, or various scalenohedra.

Amethyst: extremely powerful protective stone, aids against psychic attacks, blocks stress, promotes calming or can stimulate where appropriate. #minerals #nature #rocks #color #crystals #amethyst
Rare rock collecting is definitely not for the novice, unless you simply want to buy rare rocks. If you plan to select rare rocks on your own, expect adventure and lots of travel. Rare rocks can include such things as precious gemstones, ancient fossils or pieces of outer space thrust at the Earth's surface. But here, we have rare rocks, trees and more! Click picture to see more.
The amethyst is known as the Bishop's Stone and is still worn by Catholic Bishops. The amethyst symbolizes piety, humility, sincerity and spiritual wisdom. It is a dream stone and used to help insomnia. Amethyst is used for problems in the blood and in breathing problems. Amethyst crystal clusters are used to keep the air and life force in the home clean and positive. Amethyst is a gemstone often worn by healers, as it has the power to focus energy.
