Short answer different type of stones and gems
There are many types of precious and semi-precious stones and gems, including diamonds, rubies, emeralds, sapphires, topaz, peridot, amethysts, opals, turquoise and pearls. Each type of stone has unique characteristics such as color, hardness and rarity that determine its value.
How Different Types of Stones and Gems are Formed: An Overview
Gemstones and precious stones, with their stunning colors and intricate patterns are some of the most coveted natural resources in the world. They have been used for centuries for ornamental purposes and have become a representation of wealth, beauty, and power.
But have you ever wondered about how different types of stones and gems are formed? The process is truly fascinating. From volcanic eruptions to sedimentary rocks, there are several ways in which these exquisite creations come into existence.
Let’s take a closer look at some common types of gemstones and learn about their formation:
1. Diamonds: Formed approximately 100 miles below the Earth’s surface under extreme heat and pressure. These rare beauties spend millions of years slowly making their way upward through volcanic pipes where they can be found trapped within igneous rock formations.
2. Emeralds: Taking on average more than a million years to form through hydrothermal processes or pegmatite deposits that occur when veins of molten minerals solidify within cracks or fissures deep underground.
3. Rubies: Being formed from crystallized aluminum oxide over hundreds upon thousands of years that then react with trace amounts of chromium create rubies’ vivid red coloration.
4. Sapphires: Created using similar mineral formation as Ruby but instead it reacted with Iron & Titanium Before being heated by metamorphic activity inside the earth meaning originationg from Deep-ovens around one hundred kilometres beneath your feet
5. Opals: A unique creation caused by rainwater containing silica mixed with wood debris was preserved in minimal oxygen while fossilizing along geological layers ending up revealing its unique colorful characterisitics over time – thus giving birth to gems like opal adored across Australia!
These examples illustrate just how diverse the processes behind gemstone formation can be — with multiple mechanisms coming together to produce stunning end results shown as jewels appreciated throughout all cultures an generations in history! For instance Pearls are the only ones produced by living things, precious yet more affordable. Cultured pearls are formed from human intervention in natural pearl formation.
In summary, geology enthusiasts can get lost in learning about mineralogy all their lives! With so much variation and detail to each type of stone’s birthing process along with different physical properties making them special it’s fascinating to learn how certain minerals reflect light different on the surface or show modifications seen on an atomic level by spectrophotometers reflecting proudly off jewelry showcases worldwide today. Truly a unique topic for anyone interested in art and science!
Step by Step Guide on Identifying Different Types of Stones and Gems
Stones and gems come in all shapes, sizes, colors, and textures. Some are more valuable than others, but regardless of their worth, it’s always handy to know how to identify them correctly. If you’re a gemstone enthusiast or just curious about the rocks that you find on your travels, here is a step-by-step guide on identifying different types of stones and gems.
Step 1: Know What You’re Looking For
Before we dive into the identification process, first understand what kind of stone or gem you might be looking at. There are three categories to consider – igneous rocks (formed by volcanic activity), metamorphic rocks (formed through heat and pressure), and sedimentary rocks (made from accumulated sediments like sandstones).
Each type will have unique characteristics such as color variation, luster levels (how well they reflect light), transparency level s(whether or not they can be seen through)and crystal structure which will help differentiate them further.
Step 2: Observe its Physical Appearance
Now that you understand the classification system for stones and gems let’s start paying attention to physical appearance. Begin with observing size and shape. Next check for surface texture , weight distribution- density varies from stone to stone . Surface features can reveal clues about how it was formed so examine closely for cracks lines etc.
Some telltale signs such as metallic streaks may suggest whether your object is something like pyrite or hematite rather than quartz .
Color should also play an important role in this stage because sometimes certain minerals have distinguishing hue properties eg copper ores ranging from blues-green making this a crucial detail too
Edutip- Use reference books or online guides which list specific minerals alongside photographs showing these color variations clearly.
Step 3: Test Hardness
Hardness measurements distinguish one mineral from another as each mineral has varying degrees of resistance against impact Depending on degree measures people use either Mohs scale ”or Schmidt Hammer to calculate hardness
On the Mohs scale, which ranks minerals from 1(lower)-10(higher) depending on their resistance against change in shape once any external force is applied.
Talc has a number 11 and can be easily scratched with your fingernail. In contrast diamond tops it off at ten , making it one of most difficult materials able to break through but check for other gems that may resemble diamonds such as cubic zirconias or moissanites commonly used by merchants who seek monetary advantage over unsuspecting clients
Step 4: Specific Gravity Test
Specific gravity test calculates density ratios between an object’s mass and its volume . It helps differentiate two objects with similar outward characteristics like color if they have different densities Two stones being compared together should carry nearly equal volumes otherwise this could determine inconsistencies in comparison .
An example The specific gravity of amethyst ranges around (2.65-2.66 g/cm3), whereas red jasper hides a larger density due to iron presence ranging(2.6 – 2.7g/cm³).
Careful measurement via tools such ASTM standard weights will give accurate results
Identifying stones or gems is no easy feat sometimes requiring several steps before reaching conclusion This guide provides tips useful during process ensuring correct evaluation of uniqueness each stone presents Once familiarized observing physical appearance texture colors etc only then should undertake experimentation stage measuring fluctuation hardness quotients and differential volume-testing Expert analysis can always come handy especially while examining precious collections bearing high worth Proceed cautiously enjoy experience !
