MOSS AGATE AQUA NUEVA

Moss Agate is a variety of chalcedony, which is a type of microcrystalline quartz. It is formed through a combination of mineral processes that occur in the Earth’s crust. The key factors contributing to the formation of Moss Agate are silica-rich solutions and the presence of various minerals during the crystallization process.

 

 

SARAPE JASPER

Sarape Jasper, also spelled Serape Jasper, is a form of Jasper that comes from the Crazy Lace Mines in Mexico. Sarape Jasper is named after the traditional Sarape Blanket! It often has visually similar patterns as Crazy Lace, and is usually high in silicate. 

 

CRAZY LACE AGATE

 Crazy Lace Agate is a variety of chalcedony, which is a microcrystalline form of quartz that's infused with iron and aluminum and is often brightly colored and complexly patterned. Crazy lace agate is formed when layers of silica-rich ash and lava are deposited on top of each other. Over time, these layers are compacted and cemented together, forming a hard rock. The different colors and patterns in crazy lace agate are due to the presence of different minerals in the original ash and lava. 

 

APATITE

Apatite is a common accessory mineral in igneous rocks such as granite, syenite, and carbonatite. It can occur as small crystals or grains, or as large masses or veins. Apatite can be found in sedimentary rocks such as phosphorites, which are rocks that are rich in phosphates. These rocks often form in marine environments where organic matter accumulates and decays, releasing phosphates into the surrounding water. Apatite can occur in metamorphic rocks such as marble, schist, and gneiss. During metamorphism, apatite can be recrystallized or transformed into different mineral phases, depending on the conditions of metamorphism.

 

Garnet

Garnet refers to a group of minerals that share a common crystal structure but come in a variety of colors and compositions. These minerals belong to the nesosilicate family and have a general chemical formula of X3Y2(SiO4)3, where X and Y are elements that can vary. The most commonly found garnets are typically red to reddish-brown in color, but they can also occur in shades of orange, yellow, green, purple, and even colorless varieties. The diverse range of colors is due to the different elements present in the crystal structure. Garnets form under specific geological conditions that involve high temperature and pressure environments. They are typically found in metamorphic rocks, which are rocks that have undergone significant changes due to intense heat and pressure, as well as in some igneous and sedimentary rocks. The exact conditions under which garnets form can influence their composition, color, and crystal structure.

 

SUNSTONE

Sunstone is a microcline or oligoclase feldspar, which when viewed from certain directions exhibits a spangled appearance. It has been found in Southern Norway, Sweden, various United States localities and on some beaches along the coast of South Australia.

 

RED AVENTURINE

Aventurine is a variety of translucent quartz or quartzite with abundant small plate- or flake-shaped inclusions. Light entering the quartz strikes these inclusions and reflects from them. This produces a sparkly appearance known as "aventurescence." The inclusions can also impart a distinct, and often beautiful, color to the material.

 

 

LIGHT GREEN AVENTURINE

Aventurine is a variety of translucent quartz or quartzite with abundant small plate- or flake-shaped inclusions. Light entering the quartz strikes these inclusions and reflects from them. This produces a sparkly appearance known as "aventurescence." The inclusions can also impart a distinct, and often beautiful, color to the material. The most common inclusion in aventurine is fuchsite, a green chromium-rich mica. Just a few percent fuchsite by volume can impart a distinct green color to aventurine.

 

GREEN JASPER

Jasper is an opaque form of Chalcedony, which is a microcrystalline variety of the mineral Quartz. It often contains an abundance of impurities, and therefore some regard it as a rock instead of a mineral. Jasper is usually associated with brown, yellow, or reddish colors, but may be used to describe other opaque colors of Chalcedony such as dark or mottled green and orange. Some forms of Jasper are banded, and these banded Jaspers may appear similar to Agate, but unlike Agate they are opaque. When Jasper is dull and lacking interesting colors or patterns, it is not Jasper but rather Chert.

 

SMOKEY QUARTZ

Smoky quartz is a captivating variety of the mineral quartz, celebrated for its enchanting smoky-gray to brown coloration. This gemstone derives its name from its appearance, resembling the hues of smoke-infused crystal. Composed of silicon dioxide, like other quartz varieties, smoky quartz acquires its distinct color through the presence of natural irradiation and trace elements within its crystalline structure.

 

INDIAN UNAKITE

Unakite is a metamorphic rock that forms when granite is altered by hydrothermal metamorphism. During metamorphism, plagioclase in the granite is replaced by epidote to produce a rock composed primarily of green epidote, pink orthoclase, and clear to milky quartz.

 

OPAL CHALCEDONY

Chalcedony is a white, buff, or light tan, finely crystallized or fibrous quartz that forms rounded crusts, rinds, or stalactites (mineral deposits suspended from the roofs of caverns) in volcanic and sedimentary rocks as a precipitate from moving solutions.

 

BLACK OBSIDIAN

Obsidian forms when volcanic lava cools so quickly, there's no time for crystals to grow. This gives the rock a black, smooth, glossy shine. Since obsidian forms from magma, it is an igneous rock.

 

TIGER'S EYE

Tiger's-eye is a chatoyant member of quartz used for both decorative and ornamental purposes throughout history. Chatoyancy manifests as a silky, wavy shimmer across the stone. Tigers eye quartz is made up of quartz with intergrown fibers of amphibole that were altered to golden or rusty-brown limonite.

 

BLACK ONYX

Onyx is a type of chalcedony, which is a microcrystalline form of quartz. It is a banded variety of chalcedony that forms in concentric layers of different colors. Onyx typically has a black base with white or colored bands. The colored bands can range from shades of brown, red, orange, yellow, green, blue, and purple.

 

 

CLEAR QUARTZ

Quartz is a hard, crystalline mineral composed of silica.  The atoms are linked in a continuous framework of silicone-oxygen tetrahedra, with each oxygen being shared between two tetrahedra.  Quartz is the second most abundant mineral in Earth's continental crust, behind Felspar.  It is a mineral with a value of 7 on the Mohs scale of hardness.  

 

SODALITE

Sodalite is a tectosilicate mineral, with royal blue varieties widely used as ornamental gemstone. Although massive Sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the Sodalite group with Hauyne, Nosean, Lazurite, and Tugtupite. A 5.5 - 6 on Mohs Hardness scale.

 

 

ROSE QUARTZ

 Rose quartz is always found in massive form, so it lacks regular, flat crystal faces. It's typically found in pegmatites, but also occurs in hydrothermal veins. Research has shown that rose quartz owes its delicate pink color to microscopic inclusions of aligned silicate mineral fibers.

 

CARNELIAN 

Carnelian is a captivating gemstone renowned for its warm and vibrant colors, ranging from light orange to deep reddish-brown. It belongs to the chalcedony family, which is a type of microcrystalline quartz. With its rich history, cultural significance, and various practical applications, carnelian has captivated human attention for centuries. Carnelian is a translucent to opaque gemstone with a distinct vitreous luster. It is composed primarily of silicon dioxide and exhibits a hardness of 6.5-7 on the Mohs scale, making it durable enough for various uses. The gemstone’s vibrant colors are due to the presence of iron oxide impurities.

 

RED JASPER 

Red Jasper is an aggregate of micro granular quartz and cryptocrystalline chalcedony. The red color is due to iron inclusions. Red Jasper rates a 6.5 -7 on Mohs Hardness scale. 

 

AMETHYST

Amethyst is a transparent purple gemstone.  It is a variety of Quartz whose color can range from pale lilac to a deep purple with red or blue undertones.  Amethyst is considered a semi-precious gem.  The color is caused by the presence of iron compounds in the crystal structure.

 

 

SERPENTINE

The most obvious physical properties of serpentine are its green color, patterned appearance, and slippery feel. These remind the observer of a snake and that is where the name "serpentine" was derived. Serpentine is also known for its translucent diaphaneity, waxy luster, ease of being cut into shapes, and its ability to accept a polish. These properties make it a popular gemstone, architectural material, and ornamental stone.

 

GREEN AVENTURINE

Aventurine is a variety of translucent quartz or quartzite with abundant small plate- or flake-shaped inclusions. Light entering the quartz strikes these inclusions and reflects from them. This produces a sparkly appearance known as "aventurescence." The inclusions can also impart a distinct, and often beautiful, color to the material. The most common inclusion in aventurine is fuchsite, a green chromium-rich mica. Just a few percent fuchsite by volume can impart a distinct green color to aventurine.

 

 

SEA FOSSIL JASPER

Sea Fossil Jasper also called a Mariam Stone is a commercial trade name for a type of jasper that reportedly comes from the Himalayas in India, where it was formed in an ancient swamp. This stone is thought to be a blend of Hematite, mud, plants, and shell fossils. Its popularity comes from its interesting surface pattern that comes from the fossilized shells.
