How to Identify Different Types of Gem: A Guide for Beginners
Gemstones are a wonderful and fascinating aspect of our natural world. These beautiful stones come in all shapes, sizes, colors and styles – not to mention the many different types of gemstones that exist! With so much variety, it can sometimes be difficult for beginners to know how to tell one type of gemstone apart from another.
In this guide we’ll walk you through some basic steps on how to identify different types of gems. It’s great if you’re new to the subject as well as for anyone who wants a more detailed understanding of these incredible treasures.
1. Understand your observations
Firstly, before identifying any gemstone it is important that you understand what it is that you are looking at; things like its color, transparency and reflectivity will give clues regarding which stone family it belongs too. Gemologists also need tools such as magnifying lenses or microscopes depending upon the properties observed.
2. Look for Physical Characteristics
Next up when searching for different gems is physical characteristics: Hardness being measured by Mohs hardness scale (harder minerals scratch softer ones), density & specific gravity-all closely related factors but used differently while measuring technical details which also helps distinguishing between two similar looking species etc
3. Observe Colors
The range in vivid tones amongst varying light conditions determines the rarity of certain hues within particular families – however a colour itself cannot solely be used in identification without backing information present e.g fluorescence under UV light only visible with certain species.
4. Note down Location & Occurrence
Knowing where various stones can be found often plays an enormous role in their distinction – there’s obviously greater chance that diamonds might surface near kimberlite pipes rather than outcrops rich in emeralds or rubies occurring on volcanic mountains so geographical knowledge goes long way into correctly recognizing peculiarities associated with location/species alike
Lastly testing nature such Refractive index (measure taken by placing mineral on display and observing light’s journey through it) & chemical testing all add to purely observational techniques by allowing the gemologist to positively identify a specimen
While these differences may seem small, they can be incredibly important in distinguishing between different gems. By understanding physical characteristics, color range, location and testing nature for each type of gemstone you will soon become an expert on how to differentiate these stunning stones!
Exploring Types of Gem Step by Step: From Formation to Characteristics
Gems have fascinated us for centuries, captivating our imaginations with their stunning hues and exceptional beauty. These exquisite stones are geological marvels that are formed deep within the earth’s crust under extreme heat and pressure. However, not all gems are created equal, as each type differs in their formation and characteristics.
Let’s take a closer look at how different types of gems come into existence and what sets them apart from one another.
No gemstone is more iconic than diamonds – the world‘s hardest natural substance, made up entirely of carbon atoms arranged in a distinct crystal pattern. Diamond mines are usually found deep beneath the Earth’s surface where high temperatures and immense amounts of pressure combine to form these dazzling beauties over billions of years.
The unique qualities that make diamonds so desirable include their incredible light dispersion capability or “fire,” superior hardness compared to other minerals (10 on Mohs scale), excellent clarity due to few internal flaws or impurities, brilliant luster and scintillation.
Ruby & Sapphire
Both Ruby and Sapphire shine with an intense coloration derived from trace elements added during their crystalline growth. They belong to corundum mineral family consisting mostly of aluminum oxide crystals in various colors like blue, red pink or green hues depending upon concentration level of metal oxides such as chromium for rubies giving it its signature bright red hue while titanium produces vibrant shades ranging blue sapphires
Rubies also rank 9 out of 10 on Moh’s scale after only diamond which means they’re almost as hardy by nature whereas Sapphires closely follow behind ranking at 8-9 making them sought-after choices for jewelry design globally owing to tremendous durability
Emeralds differ significantly from diamonds, rubies or sapphires concerning mineral makeup since rather than being crystalline structures composed solely of molecules identical chemical composition provided naturally occurring beryl stone exhibiting trace element deposits producing luminescent green shade. The presence of Chromium or Vanadium contributes to enhanced coloration in these gemstones that are relatively easier to scratch due to moh’s scale 7.5-8, making it more vulnerable than previously mentioned gems.
Unlike other gemstones, opals come with a unique structure composed chiefly of water & silica inside layer which gives them an extraordinary iridescence in varying hues depending on mineral density and color impurities while formation through precipitation cycles over thousands of years from hydrothermal vents deep beneath the earth’s surface
The colorful play-of-light set against contrasting blackish body-tone often makes it appear like fire flames trapped within stone lending It Its enviable charm trait but this also means that Opals are far softer as compared for instance diamond rating comes out at roughly around moh’s scale variable swing between 5-6.5 i.e less hardy stones
Gems possess incredible value and beauty but acquiring knowledge about what goes into their creation helps appraisers assign desirability and thus monetary worth when combined with precise cutting techniques aimed at highlighting each uniquely decorative effect offered by individual types appeals strongly towards all parties associated with trade activities encompassing these dazzling natural gifts whose high demand is evident till date.
Frequently Asked Questions on Various Types of Gem: All You Need to Know
1) What is considered as a precious stone?
The term “precious stone” typically refers to diamonds, sapphires, rubies, and emeralds – also known by their acronym DSE (Diamonds, Sapphires, Emeralds). These are valued for their rarity, high durability and luster.
2) What distinguishes precious stones from semi-precious ones?
Traditionally it was believed that precious stones were harder than semiprecious ones. Nowadays this distinction has become outdated since we discovered many hard semiprecious minerals like alexandrite. The current classification therefore depends solely on market perception or demand.
3) Where do Gemstones come from?
Gemstones are found in mines all over the world; however certain gemstones such as ruby & blue sapphire often sourced majorly from Burma(renamed Myanmar), Mozambique & Madagascar just like Colombian emerald which is most renowned worldwide other areas yielding therapeutic stones include Sri Lanka Andhra Pradesh India Brazil Zambia Namibia South Africa Australia Canada Russia USA Kenya Tanzania etc
4) How can one test if a gemstone is genuine or fake?
Several characteristics inherent to natural gem-stones exist blemish bubbles irregularity among other signs indicating authenticity or faux formations synthetic color saturation may at times be too good leading experts tend perform tests including UV light/diamond tool scratching superset against actual properties determined glass refractive indices specific gravity hardness levels and thermal conductivity before attesting their authenticity flawlessness `the tongue-test’ or / “black-light test”- conducted by holding them under UV Rays are popular measures even though they don’t always expose every detail about the cut clarity carat weight or inclusions.
5) What factors determine the value/cost of a gemstone?
Gemstones are appraised based on their clarity, color, cut and carat weight. These four features help determine its rarity leading to its ranking as either high or low quality among various stones. Rarity heavily relies on demand; so if popularity changes overtime for one particular kind it will change how valuable the market views them at any moment.
6) Is there an ideal time/occasion to buy a gemstone?
There isn’t particularly an opportune season/month limited times may coincide with Christmas Valentine’s weddings when people gift or receive jewelry therefore retailers occasionally offer discounts sale prices alternative dealers showcase their prized selection but all year long classic rarities remain sought after investment opportunities even though some investors choose to sell during specific times when they feel the markets might yield higher profits which is always subject to change due trends new discoveries public awareness unforeseen market crashes etc although historical trends indicate that precious stones have endured several financial crises and hold intrinsic value regardless hence making them great assets and wonderful gifts anytime throughout the year!
Top 5 Surprising Facts about the World’s Most Popular Types of Gem
Gemstones have been used for centuries as symbols of wealth, power and beauty. These precious stones are found all around the world, each with their own unique characteristics and properties that make them truly one-of-a-kind. From diamonds to rubies, emeralds to sapphires – here are the top 5 surprising facts about some of the world’s most popular types of gems.
1. Diamonds – They’re not actually rare!
While we often think of diamonds as being extremely rare, this isn’t necessarily true. In fact, it’s estimated that there are enough diamonds in existence right now to supply every person on earth with a handful – if they were distributed evenly. The reason for their high value? Exclusivity is a part of marketing obviously but also because they require such precise cutting techniques and skilled craftsmanship to bring out their maximum potential.
2. Rubies – They’re members of the same family as sapphires
Rubies come from the corundum mineral family which includes other gemstones like sapphires; essentially making these two among each other’s closest relatives in terms of chemical structure! The red coloration comes from traces amounts chromium while blue-coloured ones contain titanium or iron oxides instead.
3. Emeralds – They’re more brittle than you might think
Emeralds may be known for their stunning green hue but did you know they’re surprisingly delicate compared with other popular jewellery stones? While incredibly hard (they measure at 7-8 on Mohr Hardness Scale) an emerald’s crystal structure makes it susceptible to shattering when exposed to sharp knocks or large temperature fluctuations so give your emerald jewellery extra care!
4. Sapphires – Only a very specific colour is called “sapphire”
Did you know that only blue coloured corundums can be considered ‘Sapphire?” All other colours including pinkish-orange specimens are classified under the category “fancy sapphires.” While it may be a minor detail, it’s important to note that only stones with the vivid blue hue are considered ‘true’ or ‘proper” Sapphires.
5. Opals – Each one is entirely unique
No two opals from any locality share patterns or colours and this makes them incredibly valuable for collectors as each stone has story when it comes to its formation history. What sets Opal apart is its play of colour effect: tiny silica spheres arranged in minute layers creates interesting reflection on light due resulting interference between these layer shimmers.
In conclusion, gemstones – whether you’re hoping to wear them as jewellery or appreciate them through collecting – are endlessly fascinating due not just to their beauty but also because there is so much still undiscovered about many variations! We hope this list inspires you tell stories (and crushing those pub quiz questions) the next time someone admires your ring😊.

Uncommon and Lesser-Known Types of Gem That Are Worth Discovering
Gemstones have been treasured and admired for their beauty and rarity throughout human history. From the legendary diamonds of India to the sparkling emeralds of Colombia, there are many well-known gem varieties that capture our fascination.
But did you know that there are countless lesser-known types of gems out there worth discovering? These stones may not be as famous or highly sought-after as their more popular counterparts, but they still possess unique qualities that make them special in their own way.
Here we’ll introduce you to five uncommon and lesser-known types of gemstones that are definitely worth exploring:
If you’re looking for something truly rare and exotic, then larimar may just fit the bill. This pale blue stone was discovered only recently in 1974 in the Dominican Republic and is found nowhere else in the world.
Larimar is considered a healing stone with spiritual significance among native Caribbean peoples who believe it can stimulate creativity, clarity, peace, harmony, communication skills between people,and aid emotional healing from trauma.
Sunstone isn’t actually rare; you might be surprised how often this fiery orange-pink gem appears in jewelry without being identified properly!
Sunstone belongs to the feldspar mineral family which also includes labradorite and moonstone among others.Its iridescent qualities give sunstone its characteristic glittering appearance like sunlight shimmering on water.
Sphene (also known as titanite), has an unusual green color with flashes of rainbow colors similar to opal within itself when viewed under different lights.The true color effect shows best under incandescent lighting conditions rather than fluorescent daylight due to greater oil drops reflected within each facet surface creating vibrant hues.This makes it elusive nature doubles up its appeal even further!
Throughout cultural history sphene has long been considered lucky charm among ancient civilizations.Sphene is thought by astrologers to draw wealth ,prosperity and success to the wearer as it is said to boost self-confidence and induce calmness .
Benitoite was almost unheard of until its discovery in San Benito County, California in 1907, making it one of the youngest additions to our list.
Its rarity is most notable.People find beniotites only around one specific source,the mine at San Benito county.It possesses a highly refractive blue color which shines like fluorescent when held up against light.This astonishingly blue gem has been dubbed “the blue diamond” among collectors because of how hard it is for rare gems connoisseurs to obtain.Because of this difficulty benitoite ring can be valued higher than similar sized diamonds!
5. Dravite Tourmaline
Tourmaline crystals are usually pink-red or green,but have you ever heard of dravite tourmaline?
Dravite is unique from other dark brown-colored varieties and creates an aura akin to chocolate colors through a range yellow-brown.Along with many other types of tourmalines,it holds powerful healing abilities that provide protection ,healing energy,enlightenment towards greater understanding / clarity, balance and harmony.
Apart from these five listed items,a number of precious stones on earth remain relatively unknown due to urbanisation and lack public awareness.Some examples include humboldtianum garnet, spectrolate etc.So next time if you are looking for something truly uncommon yet magnificent,don’t forget there’s plenty more outthere!
