Short answer: Types of Gems
Gems are classified into four types – precious, semi-precious, organic and synthetic. Precious gems include diamond, ruby, sapphire and emerald while examples of semi-precious gems include amethyst, citrine and topaz. Organic gems are made from living organisms like pearls or amber whereas synthetic gems are artificially created but resemble natural gems.
Step-by-Step Guide: Identifying and Classifying Types of Gems
Gems are widely known for their beauty, allure and rarity. These precious stones have been prized since ancient times for their stunning colors, incredible sparkle and fascinating history. But do you know how to identify and classify different types of gems? In this step-by-step guide, we’ll explore the key characteristics that help gemologists identify some of the most popular gems and discuss ways in which these precious stones get classified.
Step One: Look for Clues
The first thing to look for is a gem’s physical appearance. Gems come in all different shapes, sizes and colors, so pay attention to any clues that may suggest what type of stone you’re looking at. For instance, diamonds and sapphires are known for their transparent or translucent textures whereas emeralds are more opaque.
Step Two: Understand Refractive Index
The refractive index (RI) measures the way light bends as it moves through a substance. Knowing the RI number helps gemologists calculate angles at which light passes through each gemstone. This information is a huge part of identifying a specific kind of gemstone from another one while sight-testing.
Step Three: Conduct Specific Gravity Test
The Specific Gravity test measures an object’s density compared to water using buoyancy principles—when buoyed-up by water’s upward thrust due to gravity. Gemstones like diamond might have high density but low specific gravity because they’re typically lightweight given their miniature size relative to other materials used by metalsmiths.
Step Four: Observe Hardness
Another factor in identifying gems involves testing how hard they are—a procedure called “hardness test.” Modern testers scratch a mystery mineral with diamond-dust grit particles that scales 10 on Mohs hardness scale. If no mark appears on its surface after considerable use then it might be a diamond; however, if scratches appear then it’s likely not diamond as such properties would make it nearly impossible where even sapphire or ruby, which ranges up to 9, would prove too flimsy in comparison.
Step Five: Use Spectroscopy
Modern spectroscopic tools can measure a gemstone’s spectrums. The diamond’s spectra contain a range of various colors while beryl and corundum display different ones. This identification may additionally help determine the type of impurities or other substances that may remain within the material.
Now that you know how to identify gems, it’s time to classify them. Gemstones get classified based on their chemical composition, mineralogy, and geology.
Classifying Based on Chemical Composition
Gemstones are classified into two main groups according to their chemical composition—silicate minerals and non-silicate minerals. Diamonds belong to the latter group whereas garnets belong to the former one.
Classifying Based on Mineralogy
The most popular system for classifying gemstones according to mineralogy is called Dana Clssification System – another classification system is Strunz Classification System; though, Dana Classification system is predominantly used in classifications due to its simplicity and wider acceptance worldwide as compared with Strunz.
Classifying Based on Geology
Additionally, Gemstones are also classified based on their geological origin where it was formed or mined from. For example, mined emeralds may have originated in Colombia, Zambia or Brazil depending upon what region they were harvested from–and each has uniquely distinct attributes characteristic only of their respective geographic regions.
Identifying and classifying gems takes both scientific knowledge and practice—but it can also be incredibly fun! Being aware of the physical characteristics that make gems unique along with understanding specific tests like refractive index, specific gravity test or spectroscopy can guide even professionals towards uncovering precious stone’s secrets sometimes hidden beneath outer appearances. Meanwhile Geological classification method adds an additional layer by offering insight into where these stones come from reveals not just inherent significance but often a rich piece of cultural history as well. By following such an approach, anyone can start to master the art of gemstone identification and classification while still having a great time unraveling the mystery of some of the most dazzling stones in existence.
Frequently Asked Questions About Types of Gems
Gems have always been a fascination for individuals looking to accessorize or add some sparkle to their lives. From the striking beauty of diamonds to the vibrant colors of emeralds and rubies, these precious stones can elevate any look instantly.
But with so many types of gems out there, it’s easy to get confused about what makes each gem unique. To help clear things up, we’ve compiled a list of frequently asked questions about different types of gems.
1. What is the difference between a natural and synthetic gemstone?
A natural gemstone is one that forms naturally in the earth over millions of years through geological processes. A synthetic gemstone, on the other hand, is created in a laboratory using chemicals and engineering techniques that mimic the conditions under which natural gemstones form. While both are technically real gems, many collectors and enthusiasts prefer natural stones due to their rarity and authenticity.
2. What is a birthstone?
A birthstone is a type of gem or mineral that corresponds with each month of the year. These stones are believed to have special powers and attributes associated with them based on traditional beliefs and folklore.
3. What determines the value of a gemstone?
The value of a gemstone depends on several factors, including rarity (how difficult it is to find), color (the more vibrant and pure the hue, typically the more valuable), clarity (absence of visible flaws), cut (how well it reflects light), size (larger stones tend to be worth more than smaller ones) and demand (popular gems like diamonds often command high prices due to market demand).
4. Are treated gems worth less than untreated ones?
In general, treated gems are worth less than untreated ones because they have undergone an artificial process which alters their natural appearance or structure. However, some treatments may actually enhance certain characteristics like color or shine, which can increase their value.
5.What are some popular types of precious gems?
Diamonds are the most popular precious gemstones, but others include emeralds, rubies, sapphires and pearls. Many other types of gems exist that are considered semiprecious stones including garnet, peridot, citrine and amethyst.
6. What is a conflict gem?
A conflict gem refers to a precious stone that has been mined in an area where there is ongoing armed conflict or human rights abuses taking place. The production of these gems can fund or fuel these conflicts and harm workers involved in their extraction. It’s highly recommended to avoid buying any such gems as it helps contribute towards ending these conflicts.
In conclusion, knowing different types of precious stones not only enhances your knowledge but also adds an extra edge when selecting a perfect piece of jewelry suiting your occasion or mood!

How Do Types of Gems Form in Nature? Explained
Gems have always fascinated us since ancient times because of their beauty and rarity. From diamonds to ruby, emerald to sapphire; gems are found in different colors, shapes, and sizes. But have you ever wondered how these jewels form in nature? This blog will take you on a journey to understand the types of gems and how they form.
Firstly let’s understand what exactly is a gemstone? Gems or gemstones are minerals that are rare, durable and attractive enough to be used for adornments or jewelry purposes. These minerals are formed over millions of years deep inside the earth’s crust under high pressure and temperature conditions.
There are three main categories of rocks that can produce gemstones – igneous, metamorphic, and sedimentary rocks; each of these rock types forms differently from one another which leads us to different crystal structures.
Igneous Rocks:
When magma or lava solidifies inside the earth’s surface it creates igneous rocks. Some examples of igneous rocks include basalt, granite, pumice, rhyolite among many others. In most cases when molten metals cool down slowly underground they create crystals which eventually turn into precious stones such as garnet, tourmaline or amethyst depending on what minerals were present during their formation.
Metamorphic Rocks:
These rocks are formed when other rocks undergo immense heat & pressure below the earth’s surface leading them to change in nature chemically & physically thus creating new ones with unique properties. These changes can result in various gemstones like topaz, zircon or turquoise based on their chemical composition.
Sedimentary Rocks:
Lastly some gemstones such as agate and jasper come from sedimentary rocks that were originally formed by layers accumulated beneath bodies of water over long periods resulting in unique patterns which make them wonderful decorative items making modern jewelry makers & lovers alike swoon with delight.
In conclusion different combinations of temperature, minerals & pressure conditions result in different types of gems. These creations of mother nature are a rarity and ones which we treasure for generations to come. So cherish your jewelers and even more, mother earth who has blessed us with such precious gifts.
The History and Cultural Significance Behind Different Types of Gems
Gemstones have always held a special place in human history and culture. For thousands of years, these precious stones have adorned our jewelry, been used as a form of currency, and even as symbols of power and social status. But beyond their obvious beauty and material value lies a rich history that spans across civilizations and cultures around the world.
Notably, gemstones were believed to possess certain qualities or powers that could influence one’s life in various ways. For example, the ancient Greeks believed that amethysts had the power to prevent drunkenness; while the Egyptians thought the bright green emerald symbolized fertility, rebirth, and love.
Diamonds
Arguably the most famous of all gemstones is the diamond. The word ‘diamond’ comes from the Greek word “adamas,” which means “unconquerable” or “invincible,” indicating its extreme hardness – making it virtually indestructible.
Diamonds are also associated with love – a symbol of commitment when given as an engagement ring; traditionally featuring a solitaire diamond in a four-prong setting. Diamonds also signify wealth and power – from biblical times to modern pop culture references like rapper Cardi B rapping “I said I never seen some diamond in person”.
Rubies
Easily distinguished by their vibrant red color (which ranges from pinkish-red to deep crimson), rubies carry cultural significance on multiple fronts. In Hinduism, for instance, ruby was considered ‘the king of gems’; representing courage, good luck & vitality; worn by royalty or people seeking divine blessings.
Moreover, rubies valued today are large enough (and sufficiently un-heat-treated) so that no artificial elements added during enhancing techniques cloud their inner sparkle/sheen; Reflecting aristocracy like former First Lady Nancy Regan wearing her cherished ruby engagement ring on any occasion possible.
Emeralds
For centuries green emeralds made up prized possessions for wealthy individuals and even in the royal family, as it was believed to bring good luck and symbolize rebirth, strength and youth. Today, the Colombian region produces some of the world’s most valuable emeralds fetching millions a piece.
Pearls
Pearls are not traditionally classified as gemstones but, due to its hard structure composed of calcium carbonate crystals or “nacre,” it has been long valued for their natural beauty. Cultured pearls specifically were usually worn by royals in kingdoms as a signifier of wealth through strands & pendants; even auctioning off one of Cleopatra’s pearl earrings for $2 million at Christie’s Auction House in 2010.
Sapphires
Though sapphires come in many different colors – including pink and yellow – they’re often recognized for their blue hue. From home decor to jewelry pieces, sapphire is representative of deep loyalty, wisdom and nobility across various cultures such as Indian astrological practices dating back over 2,000 years ago.
Ultimately gems like these have served numerous purposes throughout history from spiritual beliefs to tangible symbols of status. Their colorful history allows them still be carefully crafted into statement pieces today that reveal more than just exceptional beauty but also value ingrained by different periods across generations.
Investing in Gems: Which Type is Right for You?
Investing in gems can be a smart financial move, but it takes knowledge and strategy to make a wise investment. It’s crucial to choose the right gemstone that aligns with your investment goals to ensure its value will appreciate over time.
There are many factors to consider when selecting a gemstone, including rarity, beauty, durability, and market demand. Here are some of the most popular gemstones for investment:
1. Diamonds: Diamonds have long been considered a safe and profitable investment option. Their durability and timeless appeal make them an enduring symbol of love and commitment which ensures perennial interest in them. However, their high price tag makes them less accessible to newbie investors.
