Pink opal is formed by bubbling water near volcanic ash. It dissolves the silica and forms in nodules from volcanic activity. Most specimens contain pink opal mixed with minerals such as rhyolite. These beautiful specimens are only found in Peru and Australia.

Moss agate is a semi-precious stone. It is a variety of Chalcedony and it formed from silicon dioxide. The field of this stone is a milky white or clear quartz with blue and green inclusions that form as a result of oxides in the mineral. The dendritic inclusions are mainly made from manganese or iron that grow into patterns to give it the moss look.

Lapis lazuli forms near igneous interferances where limestone or marble has been altered by contact metamorphism or hydrothermal metamorphism. In these rocks, lazurite replaces portions of the host rock and often develops within certain bands or layers which can include other minerals such as pyrite and white calcite. Lapis Lazuli is mostly found in Afghanistan but can also be found in Chile, Russia, Canada, Argentina, Pakistan, and the US. Within the US, these stones can be found in Colorado, California, and Arizona.

If your birthday is in February, you are probably familiar with this beautiful crystal. Amethyst is made mainly of quartz. Their purple color comes from its aluminum and iron properties and can range from pink to a dark purple. This popular gemstone originated in ancient Greek times. Now, higher quality amethyst is mainly found in Brazil and Uruguay but can be found all over the world, including the United States. Hematite is an iron oxide that is formed through various geological processes including weathering, sedimentation, metamorphism, and hydrothermal activity. The red color in this variation of hematite comes from white light interacting with irregular hematite particles.

Stichtite is a secondary mineral that forms as a result of the interaction between Serpentine and chromium. This is a hyrdothermal interaction where the chromium and other fluids infiltrate the Serpentine and create Stichtite. This crystal is famously found in the Dundas mineral field in Tasmania, Australia.

Dream amethyst (also known as Chevron Amethyst) is a natural mineral formed when amethyst and white quartz fuse together while cooling down off after a volcanic eruption. The amethyst that fuses to the white quartz creates the chevron-like shapes in the crystals. The main areas Dream Amethyst can be found is Brazil, Namibia, and Morocco.

Labradorite is a type of feldspar that gets it's flashy colors from intergrowths within the mineral. Light then travels through these intergrowths and displays its beautiful colors. These colors can range from purples and blues to greens and yellows. This mineral gets its name from where it was originally discovered, in Labrador, Canada. This mineral was also found in Finland during WWII and was also known as "Falcon's Eye".

Rhodonite is a silicate mineral usually found in metamorphic rocks that are known to have other manganese minerals in them. The manganese is how Rhodonite gets its color. This specific variation of Rhodonite is found in the San Martin Mine in Peru.

Tiger's eye is a semiprecious stone that is formed when parallel veins of crocidolite fibers are first altered to iron oxides and then replaced by silica. As a result it is more opaque, and creates a rich yellow to brown color. Tiger Eye can be found in Australia, Burma, United States, Brazil, China, and many other countries.
