Glossary of Terms - Mineralogy/Crystals


My interest in Mineralogy started as a child. I loved rocks! 

During my twenties I started making jewelry. I love unique one of a kind pieces. During this time I also took some classes at a local college which gave me a great basic foundation about how the Earth works to birth theses beautiful pieces of natural art. 

I have put together the scientific part of what I have learned about gems & minerals as a Glossary of Terms. On July 13 I will be speaking about the glossary of terms on A Gang of Girls Radio 

Here is the information I have gathered for all of us to share!

Glossary of Terms

Category - is the process in which ideas and objects are recognized, differentiated and understood. 

Formula - chemical compound.

Crystal Habit - Crystal habit is an overall description of the visible external shape of a mineral. This description can apply to an individual crystal or an group of crystals 

Cleavage - is the tendency of crystalline materials to split along definite crystallographic structural planes.

Fracture -  a fault that divides the rock into two or more pieces. 

Chatoyancy- is an optical reflectance effect seen in certain gemstones. Coined from the French "œil de chat," meaning "cat's eye," chatoyancy arises either from the fibrous structure of a material, as in tiger eye quartz, or from fibrous inclusions or cavities within the stone, as in cat's eye chrysoberyl. 

Luster- a description of the way light interacts with the surface of a crystal, rock or mineral

Streak - the color left by a mineral dragged across a rough surface

Stalactite  - from the Greek stalasso, ‘to drip’, and meaning ‘that which drips’ is a type of speleothem (secondary mineral) that hangs from the ceiling of limestone caves. It is a type of dripstone. 

Stalagmite- from the Greek stalagmitês, stalagmias, ‘dropping, trickling’ is a type of speleothem that rises from the floor of a limestone cave due to the dripping of mineralized solutions and the deposition of calcium carbonate. This stalagmite formation occurs only under certain pH conditions within the underground cavern. 

Vitreous minerals have the lustre of glass. (The term is derived from the Latin for glass, vitrum.) Common examples include calcite, quartz, topaz, beryl, tourmaline and fluorite, among others.

Crystallographythe science dealing with crystallization and forms and structure of crystals.

Gem Remedy - like the Bach Remedies -made with water, brandy and the gemstone. The stone is placed in a glass bowl of spring water for a certain amount of time and placed in the sunshine, sometimes in the moonlight. Take the crystal out of the water and pour the energized water in a dark bottle, filling it halfway. Pour brandy to fill it. Shake bottle and place in a cuboard for two weeks. Shake the bottle periodically. This is the mother remedy. From this you will fill a smaller bottle with a dropper up 2/3 full with spring water and top it off with the mother remedy. Put 2-3 drops of remedy in a glass of water 3 times a day. The Gem remedy can also be put in bath water and used as a room spray. Check out the recipes different gems & minerals.
