Short answer: Types of gems include precious and semi-precious stones. Precious stones include diamonds, rubies, sapphires, and emeralds. Semi-precious stones include amethyst, citrine, turquoise, garnet and many more. Each gemstone has unique physical properties and significance in various cultures.
How to Identify and Classify Different Types of Gems
Gems or gemstones are minerals that have been cut and polished to enhance their inherent beauty. They are used for various purposes like jewelry, decorative items, and even in industrial applications. However, identifying different types of gems can be a challenging task as they come in a wide range of colors, shapes, sizes, and physical properties.
To begin with, let’s take a quick look at the four main classifications of gems based on their composition – mineral gemstones, organic gemstones, rock gemstones and synthetic gems.
Mineral gemstones are naturally occurring minerals that possess the necessary properties for use as a decorative item. These minerals usually grow inside rocks or earth’s surface under specific conditions. Examples include diamonds (carbon), rubies (corundum), sapphires (corundum) and emeralds (beryl).
Organic gemstones are produced from living organisms such as plants or animals. Examples include pearls (oyster shells), amber (fossilized tree resin) and coral (marine animal secretes).
Rock gemstones refer to those that are made up of compacted mineral grains from volcanic activity or sedimentary rock layers. Examples include lapis lazuli (a combination of minerals incl sulfides) and agate/amethyst/ quartz (silica-based minerals).
Synthetic gems refer to those manufactured in laboratories through the process known as artificial crystal synthesis. Examples include cubic zirconia which is a type of laboratory-produced diamond.
Now that we’ve covered the classifications let’s dive into how to identify each type:
1) Mineral Gemstones Identification:
The easiest way to identify mineral gemstones is by observing their color when exposed to light; most will produce vibrant colors depending on a few factors such as its origin place due to trace amounts of impurities during growth phase etc). Additionally when physically examined in light, specific patterns and characteristics become visible that can help identify them.
2) Organic Gemstones Identification:
Organic gemstones tend to have completely different physical characteristics from their mineral counterparts. One way to differentiate is by exposure to heat – organic gems like pearls will break down due to heat while most ores will remain unaffected. Similarly, most organic gems are much more delicate and will scratch/smudge easily as compared to rocks/minerals (for example if you rub an amber on your sleeve, it will get smudged).
3) Rock Gemstone Identification:
Rock gemstones are only a little bit harder than the previous category of organic gems so they’re also delicate in nature but require a bit more force before being degraded. To identify these types of stones we use visual cues such as mineral streaks (color left behind when rubbed against paper), cleavage (shape/formation when broken or cut), fracture patterns etc.
4) Synthetic Gems Identification:
Synthetic gemstones are perhaps the easiest to identify thanks to their common shapes and extreme precision in cuts making them quite indistinguishable from natural ones at times; however they also exhibit tell-tale signs such as how it was made which includes uniformity, presence of air bubbles within crystal structure or lack thereof, plus a general consistency – all elements of manufacture!
In conclusion, differentiating between different types of gems may seem like a daunting task at first glance however with some attention to detail anyone can decipher what stone they’re looking at right off the bat. Learning the fundamental differences between mineral versus rock versus synthetic versus organic material science type jewelry options should be a great start for anyone interested in learning about how minerals contributed so greatly towards human civilization! Happy hunting!

Rubies: Often seen as fiery red like flames these can signify passion or love.Their vibrant hue has made them popular choices even among royalty., while ruby quality is determined by factors like cut shape defect density intensity tone along with secondary hues (orange-pink) also playing roles.
Sapphires: Sapphires are blue – but not always! They actually come in a variety of tones from pale pastels to rich midnight blue hues. The more intense shades (often from Kashmir, Burma, and Madagascar) tend to be among the most valuable. Like most gemstones, sapphire’s quality is based on carat size, intensity of color and clarity.
Pearls: Known as the only “gemstone” that isn’t mined from earth- pearls grow naturally within the glands of certain mollusks such as oysters. Once their shape arises some people even saying they resemble drops due to their shape! Cultured pearls tend to be less rare than their natural counterparts; however, pearls remain highly valued in spite of this because they can symbolize wisdom!

Gemstones have captivated the human mind for centuries. Their beautiful nature and rarity make them some of the most sought after materials in the world. Gemstones are classified as precious or semi-precious based on their rarity, quality, beauty, and durability.

Its natural hardness makes it incredibly durable, hence its ranking at 10 out of 10 on Mohs Scale (a mineral scale used to measure hardness). Diamonds are mostly used as centerpieces for engagement rings and earrings pieces worn during special moments.
Rubies are characterized by their blood-red color which is caused by traces of chromium within its chemical structure.

A prized possession among royals due to their soft green color, emeralds originated from Columbia before they became discovered across South America and Africa where they were thought believe healing powers similar our modern-day crystals use.. Due to high demand emeralds sometimes come with price-tags equivalent to that diamond accessories pricing range along with comparable rankingin terms of crystal wearing ability though not tough enough like sapphire’s or ruby’s sturdiness with only relative value placed about 8 on the Mohs scale.
Starting from the sapphire’s which are among the toughest gemstones, Sapphires also rival diamonds as a popular precious stone.
