Euclase

1. Introduction & History

Euclase is a beryllium silicate mineral known among rare-stone collectors and gem lovers as a 'hidden treasure.' It was first named in 1792 by the renowned French crystallographer René Just Haüy.

The name comes from the Greek Eu ('well') and Klasein ('to break'), referring to its perfect cleavage, which lets it split cleanly and easily.

Although chemically similar to beryl-family gems such as Emerald and Aquamarine, it is produced in tiny quantities and is far rarer. It is difficult to cut, so faceted stones seldom reach the market — yet its clear, transparent blue captures the eye at once.

2. Symbolism & Energy

Euclase symbolizes 'clear intuition' and 'truthful expression.' Its clean, refreshing energy clears the head and helps sort out tangled thoughts and emotions.

3. Color & Quality

Euclase ranges from colorless and transparent through pale green and blue-green to an enchanting deep blue.

• Most Valued Colors: Transparent, intense neon blue to blue-green specimens reminiscent of Emerald or top-grade Aquamarine are valued most highly.
• Visual Character: Its excellent vitreous luster gives off crisp, sharp reflections in the light. Unusual bi-color specimens, in which colorless and blue blend like a gradient within a single crystal, are also popular.

6. Care Guide

With a Mohs hardness of 7.5 Euclase is hard, but its perfect cleavage makes it very vulnerable to impact.

• Cleaning: Dissolve a mild detergent in lukewarm water and wipe gently with a soft cloth. Never use ultrasonic or steam cleaners — the stone can split along its cleavage.
• Cleansing: Resting it on a clear quartz cluster, sound (singing bowl) cleansing, or smoke cleansing with sage or palo santo are recommended.
• Cautions: Protect it from strong impacts and drops. Store it on its own so it does not knock against other jewelry or stones.
