Natural Agate comes in different kind of formation. Prcelas agate is also one of them. Origin Mexico. Agate is a variety of chalcedony, which comes in a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. 

Agate usually forms in rounded nodules or knobs which need to be sliced open to bring out the internal pattern hidden in the stone.

The dendrites in dendritic agate are iron or manganese inclusions and are usually brown or black in color. Though they appear organic due to their fern-like structure, they are actually inorganic; they are traces of iron or manganese from neighboring rock that crystallize after seeping through fine surface fractures in the agate. Dendritic agate can be tricky to cut because the dendritic inclusions occur at various depths in the rough stone. The lapidary needs to cut the material to expose the most interesting patterns. The famous Russian jeweler Carl Faberge, who was commissioned by the Russian Imperial Court from 1885 to 1916, used dendritic agate along with diamond and other precious stones for many of his pieces. Dendritic agate is prized in Russia as a stone of longevity, good health and prosperity. Like other types of chalcedony, dendritic agate has a hardness of 6.5 to 7 on the Mohs scale, a specific gravity of 2.59 to 2.67 and a refractive index of 1.530 to 1.540. Since chalcedony has no cleavage it is quite durable and can be used for a wide variety of jewelry designs.

Fossil coral is a natural type of gemstone formed by ancient corals. The proper name for fossil coral is 'agatized coral' or 'agatized fossil coral', because during formation, the coral remains are gradually replaced with agate, a variety of naturally occurring chalcedony, or microcrystalline quartz. When prehistoric corals are fossilized through replacement with agate, the fossil coral forms through hardened deposits left by silica-rich waters. The entire process can take over 20 million years and occurs only under very unique geological conditions. Corals are marine animals and it is their skeletons that are fossilized and preserved, often leaving flower-like patterns in the stone. Fossil coral should not be mistaken for endangered or protected reef coral or precious coral. It is considered to be a type of agate or chalcedony, rather than a type of coral, due to its silicon dioxide composition (SiO2). Coral deposits have been mined and commercialized for their high calcium, potassium, magnesium and sodium content, and are often used for the making of health and drug supplements. Fossil coral is used in industrial fertilizers and water purification filters because it can remove chemical impurities such as chlorine and formaldehyde.
