Aragonite Origins & Background
Aragonite is a calcium carbonate mineral closely related to Calcite. Although the two share the same chemical formula, they differ in crystal structure, giving Aragonite its distinct growth habits and physical properties.
Aragonite is best known for forming striking crystal clusters, including starburst, spray, and branching formations. These structures reflect rapid crystallization under specific environmental conditions.
In addition to crystalline forms, Aragonite commonly occurs in massive form. This material is often compact, banded, or intergrown with other calcium-based minerals, making it suitable for cutting and polishing.
Aragonite is found worldwide, with notable deposits in Spain, Morocco, Peru, Mexico, Namibia, Pakistan and the United States.
Some well-known lapidary materials sold under trade names — such as Caribbean Blue Calcite — are actually natural combinations of Aragonite and Calcite. These mixed compositions reflect geological transitions rather than artificial assembly.
Aragonite Geological Information
Aragonite is a polymorph of calcium carbonate (CaCO₃), meaning it shares its chemical composition with Calcite but crystallizes in a different structure.
It forms primarily in low-temperature environments, including sedimentary deposits, hydrothermal systems, caves, and marine settings. Aragonite is also a major component of shells, corals, and some reef structures.
Crystalline Aragonite typically forms as orthorhombic prisms, needles, or radiating clusters. These forms often result from rapid mineral precipitation under conditions of high saturation.
Massive Aragonite forms when crystals grow too densely to develop distinct faces. This material often occurs alongside Calcite, forming layered or blended structures that are visually striking when polished.
Common Geological Occurrences
- Sedimentary limestone environments
- Cave formations and stalactitic growths
- Hydrothermal deposits
- Marine and reef-associated environments

Aragonite Crystal Care & Ownership Advice
⚠️ Handling:
Aragonite is softer than Quartz and can be brittle. Crystal sprays and clusters should be handled gently to avoid breakage.
☀️ Sunlight & Heat:
Generally stable in indirect light, but avoid excessive heat which may cause dehydration or structural stress.
🧼 Cleaning:
Avoid soaking. Clean using a dry or very lightly damp soft cloth or brush. Do not use acidic cleaners.
📦 Storage & Display:
Store away from harder stones. Clusters should be displayed where they are protected from vibration and handling.

Calcite Origins & Background
Calcite is one of the most abundant and widely distributed minerals on Earth and forms the structural foundation of many geological environments. It occurs in an extraordinary range of colors, crystal habits, and formations, making it one of the most diverse and fascinating mineral families available to collectors and crystal enthusiasts.
The name Calcite derives from the Latin word calx, meaning lime. Calcite has been used throughout human history for construction, sculpture, pigments, and tools — as well as for metaphysical and spiritual purposes in many ancient cultures.
Calcite occurs worldwide, with notable deposits found in Mexico, Iceland, Brazil, China, Madagascar, the United States, and across Europe. Different localities produce distinct crystal forms, colors, and optical properties.
Calcite is known for forming some of the most visually striking crystal habits, including scalenohedrons, rhombohedrons, dogtooth crystals, massive formations, stalactites, and fibrous aggregates. Many popular varieties — such as Blue Calcite, Orange Calcite, Honey Calcite, Green Calcite, and Caribbean Blue Calcite — all belong to the same mineral species.
Calcite Geological Information
Calcite is a calcium carbonate mineral (CaCO₃) and crystallizes in the trigonal crystal system. It forms through a wide variety of geological processes, including sedimentary deposition, hydrothermal activity, and biological accumulation.
Calcite is the primary component of limestone and marble and plays a critical role in Earth’s carbon cycle. It can precipitate directly from solution, form through metamorphism, or grow biologically in shells, coral, and skeletal structures.
One of Calcite’s most distinctive physical properties is its strong cleavage — it breaks cleanly in three directions — and its well-known optical double refraction, most famously demonstrated by Iceland Spar.
Common Geological Occurrences
- Sedimentary limestone and marble
- Hydrothermal veins
- Caves, stalactites, and stalagmites
- Association with Aragonite, Quartz, Fluorite, and other carbonates

Calcite Crystal Care & Ownership Advice
⚠️ Handling:
Calcite is relatively soft and easily scratched. Handle with care and avoid contact with harder minerals such as Quartz.
🧼 Cleaning:
Avoid acids, vinegar, or harsh cleaners. Calcite can be gently wiped with a dry or slightly damp cloth. Prolonged water exposure is not recommended for polished pieces.
☀️ Light:
Most Calcite varieties are stable in light, though some colored forms may fade with prolonged intense sunlight.
📦 Storage:
Store Calcite separately or wrapped to prevent scratching and edge damage.
