Short answer different gem types
Gemstones come in various forms, some of the most popular ones are diamonds, rubies, sapphires, emeralds and pearls. Different minerals such as quartz or topaz also make up a wide variety of precious gems with unique color palettes depending on their trace elements. Each has its own value that depends on characteristics like purity and rarity. They have been suitable for decorating jewelry reducing to fine particles creating gem powder used in cosmetics products nowadays due to softness.
How Different Gem Types are Formed and Mined
As a lover of gemstones, itâs fascinating to learn about the various ways in which these sparkling beauties are formed and mined. From rare diamonds to vibrant emeralds, each type of gemstone has its unique history that is worth exploring.
Diamonds are the most well-known precious stones, but how do they actually form? Diamonds were born deep within the Earthâs mantle over 1 billion years ago under intense heat and pressure. These carbon-rich rocks rise up through natural pipelike channels called kimberlite pipes or lamproite pipes found in ancient volcanic rocks as deep as 700 kilometers below earthâscrust. Most diamond mines can be found along these pipe deposits.
Another popular gemstone is Emeralds â with stunning shades of green like lush forests; glamorous emerald stones make for highly desired jewelry pieces. Emeralds are generally created when certain minerals such as beryl get fused together with other elements like chromium or vanadium during naturally-occuring geological processes revolving around intense heat and high pressures beneath the Earth crust. Sometimes small amounts of iron also get present giving them slight tinges of yellowish-green or blue tones
Sapphires, on the other hand, are composed mostly of an aluminum compound known as corundum; hence acquiring their characteristic hardness making them suitable for daily wear fairly tougher gems than others thereby being perfect for everyday jewellery marking itself niche enough in terms identification easily from lab-grown versions Another rock-forming process contributes immensely to sapphire-making where immense pressures push hot fluids into cracks within igneous rock bodies causing epitaxial layers composing concentrated mineral samples producing pure colors depending on amount/type impurities present therein
Rubies have often been seen adorning royalty because theyâve had an enchanted glowing red color exuding grandeur unparalleled since ancient times! Red colour arises when traceable levelsof the element Chromium combine at proper concentration ranges with Aluminum Oxides forming redâclay sized plates over millions of years ago crystallizing under similar high-pressure situations as that giving birth to sapphires Organic minerals present like ilmenite and rutile hence give the gemstone a trademark sheen
Meanwhile,Tanzanite is lesser-known yet equally striking; In 1967, large deposits of this rare blue-violet gem were fortuitously stumbled upon in Tanzania. Tanzaniterose through unusual circumstances where metamorphic changes within earthâs lithosphere brought about considerable changes on rocks along magnesium-rich magma accelerating gradual formation of zoisite mineral mix latter which went ahead cooling down into peculiar âblueberryâ-like structures now popular worldwide more prominently associated with Africa owing to their origin.
Picking up a gemstone isnât just another ordinary shopping spree â each has an unparalleled history attached behind them something which visually captures oneâs heart! Do let us know your thoughts or any interesting anecdotes you might have experienced while exploring gems yourselves!

Different Gem Types: A Step-by-Step Guide to Identification
Gemstones have always been an object of fascination for people due to their beauty, rarity, and cultural significance. Gemologists use several methods to determine the identity of gemstones based on physical and chemical properties such as refractive index, specific gravity, hardness, cleavage, color, fluorescence etc. In this article we will discuss some common ways you can identify different types of gems.
1. Diamonds
Diamonds are known as the hardest mineral in existence because they consist entirely of carbon atoms arranged in a lattice crystal structure. The most important characteristic that distinguishes diamonds from other gemstones is their brilliant fire and scintillation (reflection) causing them to sparkle like no other natural stone under light or illumination.
To identify diamonds use either a loupe magnifying glass or microscope with high resolution up to 20x magnification that allows examining internal flaws called âfacetsâ. Another way one can quickly check if a diamond is real is the Fog Test â exhaling onto its surface; it should disappear immediately without leaving any trace behind.
2. Rubies
Rubies belong alongside sapphires (both Corundum family species) and while similar looking may differ greatly depending where found globally against other factors â Ruby shows variable grades of reddish-pink colored hues across different cuts with predominantly stronger pigments indicating higher quality / value specimens over those more muted
One way to test rubies involves measuring their density using scales combined with determining the refractive indices after immersion into water or oils bath options which permits comparing samples observed incidentally side-by-side through loupes or binocular microscopes after exposure time durations before comparison confirm consistency coming only from rubiesâ quality classing
3. Emeralds
Emeralds featuring vivid green colord are popularly associated with spirituality in many cultures around world though typically thought lucky charm & birthstone linked May birthdays too This beryl group mineral composition enables wide variation between shades within same size that serve in determining an emeraldâs quality.
To identify them, first assess their color and tone as well authenticity with a magnifying glass or microscope; commonly synthetic emeralds too are created by laboratory process involving flux growth method i.e where molten metals mix. It isnât detectable by the naked eye but results in slightly differently structured crystal formation compared to naturally-formed stones.
4. Sapphires
Sapphires known Corundum family member highlight blue hues which range from near-colorless (transparent white) all way through intense indigo shades Indefinitely variegated brilliantly toned when shaped precisely creating deep-dish symmetry for best reflection of internally stored light beams producing visually impressive glitter
Identification includes visual evaluation under different ranges lighting options like broad-spectrum natural ambient daylight/bulbs containing multiple frequencies visible spectrum alongside laboratory long-wave UV emissions. One can also use ultraviolet light source to confirm if it is real based on presence/absence fluorescence effect occurring after exposure.
5. Aquamarines
Aquamarine stone relatives belong Beryl family featuring subtle bluish-green coloration, appealing clarity for seeing things inside its structure, transparency & hardy durability making them fit easily into jewelry designs without risk issues during day-to-day wear-and-tear activities
Aquamarine testing techniques require special equipment allowing reliable index of refraction readings while cross-checking measurements against expected data standards plus combinations spectral analysis ensuring accuracy correctness conclusively decipher identification classification type purposes involved.
In conclusion identifying gems goes beyond simply deciding if they are âreal,â each species has distinct qualities that must be examined and considered before definitive answers can be reached- proper assessments utilizing both standard optical test tools alone forming overall methodology involved extracting authentic identification parameters given varying natures specific cases required consistently throughout industry alike â these amongst many others help certify genuine article dependent usage context suitability towards customer preferences plus budget constraints

Top 5 Fascinating Facts About Different Gem Types
1) A Diamond is Forever- But Did You Know Itâs Made from Carbon?
Most people know that diamond is the hardest natural mineral on earth but did you ever wonder what itâs actually made of? Despite being called a precious stone, diamond is formed by carbon atoms crystallizing under intense heat and pressure deep within the Earthâs mantle. Diamonds can take hundreds of millions or even billions of years to form! This means every single one has its unique journey and history.
2) The Rarity and Mystification Behind Alexandrite
Alexandrite possesses one-of-a-kind properties; it looks green when held up against light fluorescence waves similar to sunlight while appearing red when illuminated by incandescent illumination resembling traditional lighting conditions indoors. These phenomena make them used as metaphors for rarity and uniqueness.
3) Sapphires Come In Different Colors
If blue isnât quite your color preference, donât worry â sapphire occurs in almost every shade conceivable (except for red; red corundum is referred to ruby). Yellow seems strange but makes sense after learning many yellow-colored sapphires come from Ceylon Island mines which provide high levels of iron in the garnets leading towards their famous golden tone.
4) Emeralds Are Named After⊠Well⊠Green Things!?!
Emerald stones were named based on their favorite hue â green colored âsmaragdusâ which indeed signifies greenery like treesâ leaves rather than direct mentions inspired by Europe greenswards as suggested earlier was believed.
5) The Color Scale Of Rubies Varies From Pink to Deep Red
Rubies are known for their signature heart-pumping red color, but did you know that they can also range anywhere from pink to deep maroon? Rubyâs specific shade of red depends on the amount and type of impurities present at formation. The deeper the color saturation it possesses regardless of its tint level shows rubyâs value due to rarity.

The Rarity Factor: Understanding Different Gem Typesâ Worth
The world of gemstones and fine jewelry is full of wonder, mystique, luxury, and opulence. Itâs a realm that has always fascinated people since the ancient times when they were first discovered by humans for their beauty and value. From diamonds to emeralds, sapphires to rubies, pearls to opals â these precious materials have captured our hearts with their rarity factor.
In this article, weâll explore what makes gems rare and valuable by understanding the different types of gemstones available in the market today. Weâll also showcase some examples of truly remarkable pieces crafted from these exceptional materials.
The Rarity Factor: What Makes Gems Valuable?
There are several factors that determine a gemstoneâs worth such as its quality or grade (based on color/clarity/cut), size or carat weight, origin (rare stones come from limited geographical locations) and most importantly its rarity factor which encompasses all previous parameters together.
In essence, gems gain value simply because they are uncommon; just like any other product with high demand but limited supply raises its price tag. Gemologists use many methods to measure rarity such as âsupply-demand analysis,â an estimation method based on how much material is currently mined versus how much buyers want it.
To put things into perspective: though garnets can be attractive red/brown/yellow/orange/green/purple specimens one could purchase them easily within $100 while at same time Aquamarine almost twice expensive even if comparatively less bright than them â simply because aquamarines occur only in very few nodes across earth thus becoming rarer than multiple Garnet alternatives!
Different Types Of Gemstones:
Letâs dive deeper now as each type differs greatly in terms of physical properties- so do they vary in attributes dictating their value:
1. Diamonds â The King Of All Precious Stones
Diamonds are regarded globally as priceless investments due to their durable nature and brilliant fire.
