Background * History

  • Calcite is the most stable form of Calcium Carbonate and a primary Ore of Calcium. Calcium Carbonates are a very abundant group of minerals and in their purest form they are completely colorless with excellent transparency. Calcite is a primary mineral found in Metamorphic Marble.
  • Calcite is also a common constituent of sedimentary rock, such as Limestone, which often contains organic materials including the shell remains of marine organisms. The composition of Calcite is actually quite similar to various organic gemstones such as Pearl and Coral.
  • Calcite is quite soft and fragile compared to other gem types. It is primarily classified as a ‘collector’s stone’ because it lacks the hardness and durability needed for most jewelry applications. Calcite’s hardness is comparable to Amber, Coral and Chrysocoll.
  • Calcite has a distinct level of hardness and in most cases, it can be distinguished from similar materials through simple scratch testing. Quartz and Gypsum are often confused with Calcite. Calcite is much softer than Quartz and considerably harder than Gypsum. Aragonite and Dolomite can be very difficult to distinguish without testing for refractive index, specific gravity, birefringence or crystal structure.
  • Calcite in its purest form is completely colorless. Common coloring agents and impurities include Iron, Magnesium, Manganese, Zinc and Cobalt. The most common Calcite colors include white, gray, yellow, orange, green, red and blue.

Origin and Gemstone Sources

  • Mexico, USA, Iceland, Germany, Bohemia, Africa (Namibia) and the Czech Republic.


  • Calcite gemstones require great care and gentleness when it comes to cleaning. Calcite can be easily scratched and like most carbonates, it is also sensitive to acid. Avoid harsh cleaning agents, including bleach and acid. Do not use ultrasonic cleaners or steamers when caring for your Calcite.
  • When storing gemstones or gemstone jewelry, store them inside a fabric-lined box or wrapped in a soft cloth separately from other type of gemstones to prevent damage or scratches.
  • It is best to remove any jewelry before engaging in any strenuous physical activity, such as exercise or sports
