Septaria - a unique turtle stone, properties and varieties of the mineral


Septaria or turtle stone is one of the varieties of cryptocrystalline nodules in sedimentary rocks, with cracks or veins inside. It is believed that products made from this mineral are endowed with special properties.

History and origin

The first mention of turtle stone comes from the times of Antiquity, when people began to mine and process it. Septaria is a unique mineral, which is a concretion, inside the cracks of which crystals of quartz, calcite, siderite and other rocks have formed.


It is believed that the existing deposits of this mineral were formed about 50 million years ago. The formation of stones occurred on the ocean floor. The algorithm according to which the septaria was formed has already been established. First, layers of rock were layered around the core, which most often were shells and other remains of marine inhabitants. This led to the formation of nodules.

Gradually the deposits accumulated. It is believed that volcanic activity contributed to this. Erupted ash settled on the seabed, causing the death of its inhabitants. Pressure increased on the lower layers, which led to the appearance of cracks in the rock. The formed internal cavities were filled with crystals of other minerals. This process results in an unusual cloisonné pattern within the mineral. The color of the inclusions depends on which minerals got inside the core.

Septaria stone deposits

The current deposits of septaria are located on the site of dried-up oceans and seas. The mineral is not rare. It is currently mined in:

  1. New Zealand;
  2. China;
  3. USA;
  4. Morocco;
  5. England;
  6. Russia;
  7. Madagascar.

The color palette of stones and their value depends on the place where they were mined.

Physicochemical characteristics

By composition, septaria usually consist of siderite, marl, or pyrite. Marl - sedimentary rock of variable composition, consisting of clay and carbonate minerals. The composition usually contains calcite (40 - 60%), less often - dolomite. Siderite - a mineral from the calcite group, iron carbonate FeCO3.

The main part of the septaria is limestone rocks. In this case, they are formed from calcium carbonate. If the rock is formed by magnesium carbonate, then it will be dolomitic. Regardless of the underlying carbonate, unique fracture formations appear in it. They are filled with crystals of minerals, which become partitions - septa. Most often, partitions are formed by galena, calcite, dolomite, quartz, barite, pyrite.

Varieties and colors

Depending on the size of the septaria, there are 2 species, which are conditionally called "beetles" and "tortoises":

  1. The first category includes stones whose size does not exceed a few centimeters. They often have an unusual bright color.
  2. The second category includes stones that reach several meters in length.

A special variety is made by partitions that differ in shades, depending on the crystals that formed them:

  • white - limestone;
  • gray - chalcedony;
  • yellow - calcite;
  • brown - aragonite;
  • pink-red - manganese.


The high content of aragonite in the sample ensures the presence of brown veins of varying degrees of intensity. Inclusions of chalcedony give the veins a gray tint. At the same time, the inclusion of limestone provides the white color of the veins. More rare are stones that have pink and reddish streaks. Such samples are distinguished by a high content of manganese.


Now septaria, belonging to the category of "beetles", is used to make jewelry. Such specimens are rarely used as an ornamental stone. Stones belonging to the "turtle" category are often used as raw materials for creating crafts and souvenirs of varying degrees of complexity.

Large specimens are used to make mantels, countertops, and even stair treads. Polished specimens are used as a finishing material. They are often covered with facades, and are also used in the design of sidewalks and adjoining areas, etc. A crumb of this mineral is included in some building mixtures.

Stone cost

Septaria is considered an ornamental stone, not a jewelry one, therefore it is relatively affordable. The price of the mineral depends on the place of extraction, the color palette of the veins and the degree of processing. Septaria calcite, mined in Madagascar, costs about 15 euros. At the same time, the price of balloons with a diameter of up to 5,5 cm, obtained in this region, reaches 20 euros. Septaria pebbles, mined from deposits in Morocco, cost about 7 euros. Cabochons mined and processed in Russia cost up to 8 euros.

Jewelry care

Caring for jewelry made from this stone is easy. They should be protected from temperature extremes and falls. Due to the presence of cracks inside the mineral, chips may appear.

The frame should be cleaned with products specially designed for this purpose.

Products with septaria have a non-standard original look, therefore they are universal. Their soft beauty will be appropriate at a business event and in the office. They also go well with casual wear designed for meetings with friends. Decorations with a septaria will be appropriate both for a day walk and for a youth party.

How to distinguish a fake

Septaria is a relatively inexpensive ornamental stone, so it is rarely faked. However, some unscrupulous sellers try to pass off low-quality quartz and glass products as this mineral.

To distinguish a mineral, you need to carefully examine it. Inside it will be a large number of intersecting cracks. In addition, it should be tapped. The sound should be loud enough.
