The term "rarity" is used a great deal in the gem and mineral world, but what does it actually mean? In general, rarity is a measure of how difficult it is to find a particular stone. However, there are different levels of rarity, and various factors can affect a stone's rarity. Here's a closer look at stone rarity, including how minerals, crystals, and gemstones are classified.
Minerals
Minerals are the basic building blocks of rocks. They are naturally occurring, inorganic, and have a definite chemical composition. There are over 4,000 different types of minerals, and they can be found worldwide.
Some minerals are more common than others, but all minerals can be considered rare in the sense that they are not easy to find. For example, diamonds are relatively common in nature, but they are still considered rare because they are not easy to find in large sizes or with a high level of clarity.
Crystals
Crystals are a type of mineral that has a definite and repeating internal structure. This structure gives crystals their characteristic shape, which can be anything from a simple cube to a complex geometric shape.
Crystals are typically rarer than minerals because they take longer to form. For example, diamonds form over millions of years, while quartz crystals can take centuries or even millennia to form.
Gemstones
Gemstones are rare minerals or crystals cut and polished for use in jewelry and other decorative items. Gemstones are typically rarer than minerals or crystals because they are more difficult to find in large sizes or with a high level of clarity.
Diamonds, rubies, and sapphires are all examples of gemstones.
Stone Rarity Factors
Many factors affect the rarity of a stone. The first and most important is the type of stone itself. Some stones, like diamonds, are much rarer than others.
The second factor is the quality of the stone. A stone that is flawless and has a perfect colour is much rarer than one that is slightly flawed or has a less-than-perfect colour.
The third factor is the size of the stone. A large stone is much rarer than a small stone.
The fourth factor is the cut of the stone. A well-cut stone is much rarer than a poorly-cut stone.
The fifth factor is the clarity of the stone. A stone free of inclusions is much rarer than a stone with inclusions.
The sixth factor is the carat weight of the stone. A heavy stone is much rarer than a light stone.
The seventh factor is the colour of the stone. A stone that is a rare colour is much rarer than a stone that is a common colour.
The eighth factor is the origin of the stone. A stone from a rare location is much rarer than one from a common site.
All of these factors affect the rarity of a stone. The more factors that are present, the rare the stone is. A stone that is large, flawless, and a rare colour is much rarer than a stone that is small, flawed, and a common colour. The rarity of a stone is an essential factor in determining its value.
Final Thoughts
In conclusion, it is essential to understand the difference between minerals, crystals, and gemstones. Minerals are the building blocks of rocks and crystals. They are formed naturally and have a definite chemical composition. Crystals are minerals that have a regular, repeating atomic structure. Gemstones are crystals that are rare, durable, and beautiful. They are used in jewelry and other decorative items.
