Eclogite - 10 pounds

Local: Norway

1. Color: Eclogite typically has a dark green to bluish-green color, owing to its mineral composition. The green color is primarily due to the presence of omphacite, while the blue hues can come from other minerals like glaucophane or kyanite.

2. Hardness: Eclogite is a relatively hard rock, with a hardness ranging between 6.5 to 7.5 on the Mohs scale. This hardness is comparable to that of quartz or feldspar.

3. Clarity: Eclogite is not a transparent or translucent rock. It typically lacks clarity as it is composed of tightly interlocking mineral grains.

4. Luster: The luster of eclogite can vary depending on the specific mineral composition. Generally, it has a dull to greasy luster due to the presence of minerals like omphacite, garnet, and possibly other accessory minerals.

5. Density: The density of eclogite varies but is generally higher than that of typical crustal rocks due to its high content of dense minerals such as garnet and pyroxene. It typically has a density ranging from 3.3 to 3.5 g/cm³.

6. Metaphysical Properties: Due to its composition and association with metamorphic processes, it may be attributed with properties such as grounding, stability, and transformation. Some individuals may associate it with themes of resilience and strength due to its formation under intense pressure and heat deep within the Earth's crust.
