Diamonds vs. Crystals — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 23, 2024
Diamonds are a specific type of gemstone formed from carbon under extreme pressure, known for their exceptional hardness and brilliance. Crystals refer to a broad category of minerals that have a well-defined geometric shape and molecular structure.

Key Differences
Diamonds, a highly coveted gemstone, are renowned for their unmatched hardness on the Mohs scale, making them the hardest known natural material, and their remarkable optical properties that give them unparalleled brilliance and fire. Crystals, on the other hand, encompass a diverse group of solid materials where atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. This broad category includes not only precious gemstones like sapphires, rubies, and emeralds but also a wide variety of other minerals like quartz, amethyst, and salt.
While diamonds are valued for their rarity, aesthetic qualities, and industrial applications due to their hardness, crystals vary widely in value, appearance, and use. Some crystals, like quartz, are abundant and used in various applications from jewelry to electronics, while others, like sapphires, are prized as gemstones.
The formation process of diamonds is distinct and more stringent compared to most other crystals. Diamonds require specific conditions to form, which is why they are mostly found in the oldest parts of continents or in areas with volcanic activity where they can be brought closer to the surface. In contrast, crystals can form in a variety of geological environments, from cooling magma to evaporating seawater.
In the realm of jewelry and aesthetics, both diamonds and other crystals are used for adornment. However, diamonds are often the centerpiece of high-value jewelry due to their brilliance, durability, and status symbol. Other crystals are chosen for their colors, spiritual meanings, and healing properties, offering a broader palette for artistic expression.

Common Curiosities
Why are diamonds more expensive than most crystals?
Diamonds are highly valued and priced due to their rarity, exceptional hardness, brilliance, and cultural significance, especially in jewelry.
Are diamonds considered crystals?
Yes, diamonds are a type of crystal, but they are specifically made of carbon with a unique crystal structure that gives them their exceptional properties.
How can you tell a diamond apart from other clear crystals?
Diamonds can be distinguished by their unmatched hardness, high refractive index, and specific gravity, often requiring professional tools and expertise for accurate identification.
Do crystals have healing properties?
While many cultures attribute healing properties to various crystals, these claims are not supported by scientific evidence. However, individuals may find personal or spiritual significance in them.
Can all crystals be used in jewelry?
While many crystals are used in jewelry, not all are suitable due to various factors like hardness, cleavage, and overall durability.
Are synthetic diamonds considered real diamonds?
Synthetic diamonds have the same chemical composition and crystal structure as natural diamonds and exhibit similar properties but are created in a laboratory.
Can crystals form in any type of rock?
Crystals can form in various types of rocks and geological environments, but the specific conditions required can vary greatly depending on the type of crystal.
What's the most important factor in a diamond's value?
While all 4Cs (Cut, Color, Clarity, Carat) are important, the cut of a diamond significantly affects its brilliance and is often considered crucial in determining its overall beauty and value.
What's the difference between a gemstone and a crystal?
A gemstone is a piece of mineral crystal, which, in cut and polished form, is used to make jewelry or other adornments. Not all crystals are considered gemstones, but all gemstones (including diamonds) are technically crystals.
How are diamonds formed naturally?
Diamonds form naturally under high-pressure, high-temperature conditions deep within the Earth's mantle and are brought to the surface through volcanic eruptions.
