What is Perhamite?

Perhamite is a rare mineral that has fascinated geologists and mineral enthusiasts alike. Its unique properties and limited occurrence make it a subject of interest. Let's dive into some intriguing facts about this mineral.

  1. Perhamite is a phosphate mineral, specifically a hydrated calcium aluminum phosphate.

  2. It was first discovered in the United States, specifically in Newry, Maine.

  3. The mineral is named after Frank C. Perham, a well-known mineral collector and dealer.

  4. Perhamite typically forms in granitic pegmatites, which are coarse-grained igneous rocks.

  5. It often appears as small, white to colorless crystals, although it can sometimes have a pale yellow hue.

Chemical Composition and Structure

Understanding the chemical makeup and structure of Perhamite can provide insights into its formation and properties.

  1. Its chemical formula is Ca3Al7(PO4)2(OH)12·12H2O.

  2. The mineral belongs to the triclinic crystal system, meaning its crystals have three unequal axes that intersect at oblique angles.

  3. Perhamite has a Mohs hardness of about 3.5, making it relatively soft compared to other minerals.

  4. It has a specific gravity of approximately 2.5, which is considered light for a mineral.

  5. The mineral exhibits perfect cleavage in one direction, which means it can easily split along a flat plane.

Occurrence and Locations

Perhamite is not commonly found, making its discovery even more exciting for collectors and researchers.

  1. Besides Newry, Maine, Perhamite has also been found in other locations such as California and Colorado.

  2. It often occurs in association with other phosphate minerals like apatite and wavellite.

  3. The mineral can also be found in hydrothermal veins, which are fractures in rocks filled with mineral-rich water.

  4. Perhamite is typically found in small quantities, making large specimens quite rare.

  5. Its rarity and unique properties make it a sought-after specimen for mineral collectors.

Uses and Applications

While Perhamite is not widely used in industrial applications, it holds significant value in other areas.

  1. Due to its rarity, Perhamite is primarily collected for its aesthetic and scientific value.

  2. It is often displayed in museums and private collections around the world.

  3. The mineral is used in educational settings to teach students about phosphate minerals and crystallography.

  4. Some gem enthusiasts use Perhamite in jewelry, although its softness limits its practicality.

  5. Researchers study Perhamite to understand the geological processes that lead to the formation of phosphate minerals.

Interesting Facts

Here are some additional fascinating tidbits about Perhamite that highlight its uniqueness.
